bbe9a49ec3 Direct handling of pinentry execution 
We skip distro wrappers here since they interfere with stdin/out
As usual: better to have less intermediaries.

5dbcabdf26 Removed old privilege escalation model 
This commit refactors the handling of password input by eliminating
all intermediary programs and relying only on ZSh, hence improving
overall security against rootkits and such.

Also the way sudo is used is now greatly simplified and there is no
privilege escalation at boot: sudo is executed inside Tomb by being
prefixed in front of those programs needing it.

All tests passed.

a6a784f1ef swish-e indexing change and whoami cleanup 
swish-e now creates a .swishrc config file inside the tomb so that
users can tweak its configuration by hand.
whoami() is also cleaned up, pending a fix for slackware usage.

aba0fa5191 Avoid using a tempfile on every key decryption 
A tempfile was often used by Tomb in order to parse the stderr output of
gpg and detect if the password is correct or not. The tempfile was not
holding any secret information (see #162) yet this is an improvement for
Tomb's deniability since there is now much less going on in the temp
firectory.

a10d6af804 Removed handling of temporary directory 
Added the --tmp flag for manual selection of the temporary directory, whose security should really be up to sysadmins when configuring operating systems. Default is ZSh TMPPREFIX usually set to /tmp/zsh which, if not existing, will be created as world writable with a sticky bit.

This commit also includes a cleanup of commandline options and a fix to swap check.

e48c7c4a85 Added new --unsafe mode: -k cleartext 
Using the 'cleartext' name for a key will read it from stdin and
expect it to be unencrypted. This is an unsafe mode of operation,
but useful i.e. to open remote tombs by piping the key over ssh,
or using a different software than Tomb to de/crypt keys.

This commit also renames the flag --unsecure-dev-mode into --unsafe
and includes a minor fix to the last opened date shown on open.

b7f4e3a7fd Use print for non-escaped piping of secret 
after fixing issue #154 with echo here we revert to using print with
options -R -n which sort the same effect. Print is preferred since it
executes the built-in command without any possible ambiguity. We don't
want to expose secrets to an external executable in case of a simple
attack that would change the env PATH to use a rootkitted echo.

489b3582cb Disable escapes when piping secrets 
Switched to use echo with -E flag to disable escapes in keys: escape
strings were discarded cryptsetup tomb operations when they were present
in the decoded key random passphrase. Issue #154

The solution adopted here includes wrapping all cryptsetup operations to
unify the behaviour adopted.

Worth noting that this problem possibly breaks all tombs and keys
created using the unstable Tomb from git development in the past 2
months. Regression tests with previous stable releases are OK.

551a7839f5 important fix for backward compatibility to 1.2 
a grave bug has been affecting 1.3 and 1.3.1 releases, which makes keys
created with those versions incompatible with other Tomb versions.
This bug is now fixed and Tomb should be able again to open old tombs.
A script to sanitize keys will be released soon.

8d46ff46e1 new backup command to save keys on paper 
Backup simply encodes a QRCode that can be print on paper and
hidden in books or so, to keep phisical backups of keys.
The QR can be simply scanned with any smartphone, saved into a file
and reused as a key.

8e9fc7e803 Major fixes to KDF and steganography 
With the advent of a proper test suite many bugs were found and
squashed both in the way KDF and steghide were used.

Key validation func is_valid_key() now attempts recovery for keys
that have broken headers or are naked text (back-compat to old exhume).

KDF and steg now work correctly.
