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 ? git-svn-id: svn://pulkomandy.tk/GrafX2/trunk@1094 416bcca6-2ee7-4201-b75f-2eb2f807beb1
