adae1f6293 Refactor the exec callback system 
The main purpose of this commit is to ensure that exec callbacks are
registered at startup (or config reload), so that they have a chance to
run on the first update interval. Much of the code in exec.cc got
consolidated, making it easier to follow. Several checks for NULL
pointers should eliminate some obscure segfaults I noticed, as well.

During the refactoring, I implemented height and width arguments for
execbar and execgauge. The functionality was already there, but wasn't
being used. All this is accompanied by updates to the man page and
plenty of code comments.

b96f112106 Make $exec et al. use the new callback system 
I removed the code for automatic killing of stuck children, because (by admission of the person
who wrote it) it wasn't working. I also removed the $pre_exec variable, because one can use lua
to generate the config on the startup, if one wants to.

41e80b9833 Use "using namespace std;" and remove all std::'s 
I'm doing this because otherwise i'll will forget to add all those
std::'s and will lose a LOT of time finding the problems.
If you don't agree, undo this patch...
...but i hope you won't :)

01ac47d082 Implement timed_thread rewrite in C++. 
Rewrote timed_thread library in C++ using fancy new C++0x features.  The
main reason for this is to phase out poor encapsulation and C-style
function pointers.
