Small fixes.

[oscherler]

Hi,

I’ve been playing around with Lemon Launcher and here are a few changes I made:

• added a .gitignore file for autoconf/automake files;
• got rid of an extraneous database connection in handle_run;
• reversed the direction of alphadown/alphaup to match the display (down is the next letter, up the previous).

I tried my best to preserve your coding style, hopefully I didn’t let anything slip.

Best regards,
Olivier
