(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

+ * @note In MP we cannot use Random because that will cause desyncs (AIs are
+ *        ran on the server only, not on all clients). This means that
+ *        we use InteractiveRandom in MP. Rand() takes care of this for you.
