(svn r7565) -Codechange: Rework DEBUG functionality. Look for appropiate debugging levels to
use in debug.h. grfmsg() is now used as a specific debug-function for grf.

(svn r7362) -Fix (r7337): Free the freetype face after any possible error. For win32 do not use the
last font in the registry if no suitable font is found.

(svn r7337) -Feature: [win32] Add font selection by specifying a font-name, ala Fontconfig. Pretty
messy if you ask me, but this is what you get when MS hides the font API in the deepest
depths... thanks Rubidium for testing.

(svn r7333) -Codechange: [win32] Extend the OTTD2FS and FS2OTTD functions to also accept conversions
into a predefined buffer insted of using the static (global) buffer. This is useful if
the converted value will be used later on; no need to copy it somewhere else to save it.
-CodeChange: [win32] Added appropiate macros WIDE_TO_MB_BUFFER, MB_TO_WIDE_BUFFER next to
existing WIDE_TO_MB and MB_TO_WIDE that only do work when UNICODE is defined, saves
#ifdefs all over the place
