(svn r8832) -Change: rewrite the solution file generator a little so it makes project files that look more like the ones generated by respectively MSVC2003 and MSVC2005.
For some reason the internal formatting of the XML between MSVC2003 and MSVC2005 differs, so adding a file in MSVC2005 would result in basically adding the entire openttd_vs80.vcproj to the diff.

(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.
