qingy 0.5.3

- Finally the code behind the 'sleep' button has been implemented:
just set up the 'sleep' variable in config file to the
command you would like to execute for sleep mode, and
press the button in qingy...
- Now the directory qingy uses to store its temporary files
can be customized
- Added support for automatically logging in a user when
the machine powers up
- Correctly unset the DISPLAY env variable when starting a text
mode session, in case PAM provided one to us anyway.
- Added support for passing user-defined arguments to the X server.
To enhance security, as a default we now pass '-nolisten tcp'...
- Added support for AMD Athlon64 processors optimization.
- Fixed support for shadow password authentication...
- Fix stuff so that qingy links correctly against the PAM
library when compiled as a static binary.
- Session files containing spaces are now supported
- Reworked qingy PAM module to make it work with more distros
(tested on Fedora, Debian, Gentoo)
- Added support for 'retries' setting in config file
which allows user to specify how many times qingy
should try to bring its gui up before reverting
to text mode...
