graphics: Add new logo for FreeDM.

CaptainW kindly contributed a new logo for FreeDM in this thread:
http://www.doomworld.com/vb/freedoom/66962-freedm-needs-a-logo/

This uses the new logo for the title screen, menu header (M_DOOM) and
the large banner texture used in the FreeDM levels.

This fixes #12.
