b337f9174d Highlight groups the user is a member of
First non-trivial change for a while... because this involves reading from the OS, we should cache as much as we can in memory. So, group membership checking is done immediately after reading a group name, as the group structure has already been populated.

baf9f9572f Highlight link number for files with multiple links
Curiously enough, this turned out to be helpful today... Git can't
traverse symlinks, so I had to use hard links instead, and then I had to
work out which files had more than one link at a glance. If I hadn't
already had most of exa written, I'd be stuck using find!

This is behaviour cribbed from ls. Even though I've never personally used it, I'm sure someone has a use for it.

8839cf4ca5 Show file colours for symlink targets
This requires the dir field to store a reference to the path that
created it, so that path can be used to join onto the filename so it can
be properly statted.

eff87440fa Do similar for block devices and named pipes
There doesn't seem to be an io::FileType entry for character special
devices or sockets, so these fall under the io::UnknownType entry. Which
also gets highlighted in yellow, for precisely that reason.

b5a1b24bda Cache user and group names
I checked strace and it was reading /etc/passwd every time it needed to
look up a user or group. Now it only does it once per.

92b45e6908 Handle errors instead of fail!()ing
Dir::readdir and File::from path now both return IoResults, rather than just calling fail! and exiting. This allows the program to continue after an error.

355ca51617 Stop adding spaces to the end of each line
This left-aligns the final column, but the final column is the file name, so that's okay.

03ec414dfb Move file-type detection to its own module
I'd much rather have this separate, as it has the definite potential to
balloon up to a huge size and end up making the other parts of the file
module hard to read. But on the other hand, it meant making a few more
methods public on file... readability over cleanliness, I guess.

a5e404da55 Cache readdir results in a Dir object
This new object is then passed down to the File, so it can see what files are around it. This means it doesn't need to re-query the filesystem several times per file, instead using the in-memory copy.

Also, switch to using the built-in Path#with_extension method.

78771a3a3e Add a bunch more file types
And an extra level of compiled files that don't get highlighted when their source files aren't present. I don't really like having two functions that do (almost) the same thing, but I have to due to the way colouring is done.

cce20d5953 Highlight compiled files if their source is present
Compiled files with a source present (such as code.o when code.c is present) are now classified as temporary files. If the source isn't present, they're highlighted in a kind of drab colour (using the new 255-colour ability, yay!)

The code does do exists() checks on the filesystem when it could be possible to compare the files to the list of files we got from the call to readdir(), but it doesn't.

64770d0a5a 256-colour support
Add a Fixed(u8) constructor to Colour, which represents the 256 colours
that some terminals support. This means we can:

- stop using black bold to mean grey, which looks weird on terminals
  that haven't been set up to use it;
- support a *lot* more file type colours.

I'm a little suspicious of how much string allocation is being done in
colours.rs, but that's a problem for another time.

bc4df2cf3c Darken file size suffixes
I think this is necessary because 'bytes' currently has no 'B' suffix, and it's
kind of hard to distinguish a long number from a suffix.

e5e426fc60 Right-align file sizes
Currently there's only one numeric column, and that's the file size, so it gets
special treatment.

I was originally going to have a folder file size field be filled up with '-'s
as far as it could go, leaving it entirely up to the column how its field gets
formatted. But then I saw just one '-' working just fine, so I left it like
that. In the first try, columns could do anything they want when padding a
string (including changing the padding character or just changing it entirely),
but now there's no point.

This finally means that the list of columns is no longer fixed, which means it has to be generated somewhere. And guess where it got moved to? That's right, the options object! (see previous commits)

b116889abc Change format of file sizes to be shorter
I'm copying ls here because we don't really need the 'B' for bytes to be
listed every time. I think it looks better the new way. Unlike ls, don't
list directory sizes, because I've never found the pseudo-sizes they get
given at all useful.

Also, fix a bug where aligning columns didn't work when the number of
format characters (like '\x1B' and '[') were different between each
line.
