Change: Rename some freetype things to fontcache.

The font cache supports more than just FreeType as a font provider, but still used freetype in some naming.

This now uses more suitable terms.

(svn r23582) -Fix [FS#4870]: add missing characters for certain languages and the large font
-Codechange: don't remove large font glyphs because they are broken in the original font, just fix them up in openttd.grf using action A
-Change: make extra characters more consistent with the original font
All by PaulC.

(svn r11981) -Fix [FS#1698]: Use unicode glyph mapping to fix up missing/shuffled sprites in original data files instead of shuffling or skipping
sprites directly. Some required glyphs were not loaded.
-Fix: Large capital U with grave (Ù) along with some other glyphs are broken in the original data files, so do no display them.

(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.
