(svn r8807) -Feature: Add support for loading (some of) the TTDP extra chunks mainly list of GRFIDs and TTDP version the game was saved with.
GRFID list is read and active GRFs are loaded with the game if present in the data/ directory.
TTDP versioning information only works for newer versions, old versions will only give rough information but it's not worth the effort to precisely figure out what bit means what where and when.
