(svn r8810) [Configure] -Fix: "" variables if you test them, else if they are empty they return lovely errors (tnx to Celester for finding thisone ;))

(svn r8809) -Fix (r8715): accidentally removed a part of an expression.

(svn r8808) -Fix [FS#631]: do not show the 'edit sign' window for spectators.

(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.

(svn r8806) -Codechange (r7582): Remove a duplicate append of static GRF's when loading the game and hide the intrinsics of adding elements to the GRFConfig list by using an AppendToGRFConfigList function.

(svn r8805) -Codechange (r8757): DO set eol-style and keywords on new files...
