avr-gcc complains about fonts not being "const"

[sprinkmeier]

the fonts are in PROGMEM but not declared as const.
the new avr-gcc complains about that.

trivial fix, not really worth a clone/pull request etc:

This is because the tool "GLCD FontCreator2" used to create fonts from any windows font, creates the font data as static.
