Automatic builds with some inotify magic

The inotify feature in the linux kernel allows you to receive events about changed files. Using pyinotify, here is a simple script to watch for changes to source code and run "make". Everything is hard coded right now, and since I was using CMake with out-of-source builds, the directory structure is that way. It also uses the command line notify-send tool to display notifications. Perhaps some day I will make it configurable and more useful.
