(svn r8106) -Feature/Fix: Add the ability to load savegames when you don't have the exact GRF files in your list. GRF files that are found based on GRFID (but not on matching md5sum) are used instead of disabling them. This does not affect MP games, there you still need an exact match.
-GRF Window colour-codes changed a bit: Static is now grey, and compatible GRF (found locally only based on GRFID) are shown in orange. Compatible GRF's also have an orange status/warning text saying they're not the original the game was saved with.
-Loaded games with something amiss regarding GRF's will show an appropiate warning message.

(svn r8105) -Codechange: Change FindGRFConfig so that if md5sum parameter is omitted (or NULL)
only a check for GRFID is done and not on md5sum as well. Remove blanksum in the function as it's obsoleted

(svn r7759) -Merge: makefile rewrite. This merge features:
- A proper ./configure, so everything needs to be configured only once, not for every make.
- Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies.
- A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC.
- Proper support for OSX universal binaries.
- Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files.
- Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
