signs mostly done, but not noticable to the end user yet
Signs work, but are not defined in level
Removed debugging line from sign
Began to make player an mgo
removed redundant variable from sign
Fixed bug so that non-bear mgos are loaded for the first level - slightly dodgy though; this needs a reshuffle
Cosmetic only: Changed text of test sign
Player is now an mgo
Fixed bug where signs were visible in unexplored areas
Signs now message when they become visible
Clarified messages containing sign text
Player generates messages on collectable collection
fixed overly persistent messages in small worlds
Misc tiding for readability, stuff
Cells contain random numbers, for future use with randomised textures
Added variations on grass for future texture randomisation
Minor groundwork for randomised textures
Grass now has random texturing
Random tree images
random snow
