Added "Brush Factory", allowing you to run a lua script to generate (or alter, untested yet) a brush.

Added a simple (and ugly) sample script.
This needs updates to the makefile for platforms other than linux.
TODO: add a listbox to select the script you want to run. Do we have a simple API to handle filelists yet ?
