qingy 0.9.0

- Because of the following, removed '--verbose' command line argument.
- Added extensive logging capabilities. Now you have the option of having
qingy log its messages to one (or more) of console, log file, syslog.
Default is console only. Also, you can specify the log verbosity, it being
one of ERROR (default, only log errors) or DEBUG (all messages will be logged).
This should help out those people on which qingy dies with a black screen
and an unresponsive machine (other than ssh), so that they should now be able
to see why it is failing on them.
- Allow user (in graphic mode) to select a session by typing the first char
of its name. Subsequent presses of the same key will bring up any other
session names that start with the same char, if any exists.
Code kindly provided by Brian Carter <spakov@users.sourceforge.net>.
- Added support for selecting desired session during text mode login.
It will also remember latest session just like graphic login.
- Made ./configure option 'enable-x-support' actually work. Thus disabling
it will make qingy actually compile and work without X installed.
It will also make X sessions unavailable (even if X is installed)...
- Other small bug fixes.
