Patched a couple of focus bugs.

However, I've broken menubar support again. Gotta fix that sometime...
Was having trouble with a window coming up and leaving in a hurry.

This solution is a hack, but effectively works and may be adapted for later
such hacks.
Removed the code that was causing gksu to fail, and SWM now logs to /tmp.
Slight refactoring.
Patched further issues with event.c that killed compilation.

Also, windows can now be "refreshed".
Moved some things around:

 - The README is now in Markdown
 - The scripts are gone - everything is now done from the Makefile
Fixed a couple of small things:

 - Removed the build.sh script
 - Fixed some Makefile dependencies and added a code formatting target
 - Reformatted all code to the Linux coding style
 - Updated the README - apparently all the input trouble was from my
   testing setup, since it worked fine on a different Xorg instance
 - The shortcut modifier was changed to the Super key
