Ykkrosh 5778484a77 Refactor text renderer
Replace unifont with CFont and CFontManager, since the h_mgr interface
was
needlessly inconvenient.

Load the font textures through CTextureManager, to support dynamic
reloading (e.g. when resetting GL state - see #741).

Add CFontMetrics as a convenient wrapper for code that just wants to
measure text.

Fixes #1117.

This was SVN commit r14016.
