v1.1: Items are now randomised within levels.

Custom level data with notes as to where items can be placed is now included. See MAPINFO.TXT for info on how this works. It's no-longer possible to exit a level without collecting its item. A bug fix with the yorp messages, which were wrong about where levels had moved. The title screen's block colours have been randomised, and the main menu has been simplified and updated with randomiser config info. It's possible to run with the old randomiser rules with the /V1RULES option, but it required the original LEVEL??.CK1 files, which are not included.

+A few notes on randomised maps
+------------------------------
+
+As of version 1.1 of the Keen 1 Randomiser, the LEVEL??.CK1 files have been
+modified to contain additional item locations. This was suggested by
+KeenRush[1], and works as follows:
+
+- If multiple keycards of the same colour are present, these act as
+  different possible locations for one keycard. This means that all of them,
+  except for one, will be replaced with the grey sky tile.
+- The first frame of the joystick (tile 221) must be present in every level.
+  It represents a possible location for a special item (the pogo stick or
+  ship parts). Only one such item will be placed in a level.
+- Make sure these possible keycards and items are accessible without the
+  pogo stick (as it's possible that Keen won't have it), and are not
+  behind a door they're needed to open.
+- The exit door will not function until the special item in a level has 
+  been found, so it's safe to hide it somewhere far from the exit.
+  (It might be frustrating, though, if it's hidden somewhere too silly.)
