Subject: [PATCH] Fix saving/loading glyph 255 in RegisterFont

The glyph for character 255 (lower case y with two dots above it) was
rendered, but it's glyph information was not stored in fontInfo_t and
not saved into .dat file (including the ones in Team Arena).

Attempting to load it from existing .dat font files is fine because
shader name is "" and gets 0 handle. The handle was already 0 anyway.
