Subject: (svn r15027) -Merge: tomatos and bananas left to be, here is NoAI for
 all to see.   NoAI is an API (a framework) to build your own AIs in. See:   
 http://wiki.openttd.org/wiki/index.php/AI:Main_Page  With many thanks to:   -
 glx and Rubidium for their syncing, feedback and hard work   - Yexo for his
 feedback, patches, and AIs which tested the system very deep   - Morloth for
 his feedback and patches   - TJIP for hosting a challenge which kept NoAI on
 track   - All AI authors for testing our AI API, and all other people who
 helped in one way or another -Remove: all old AIs and their cheats/hacks
