Required CD key files

During a regular install of Warcraft 3, CD keys are stored encrypted into War3.mpq, in the files under the "font" directory.

In order to build a package that includes the CD key (required, or the game will not launch), you need to provide the following files in addition to the installer .mpq:
- font.clh
- font.gid

They can be extracted from a regular Warcraft 3 install with:
smpq --extract War3.mpq font/font.clh font/font.gid
