A bitmap font library for PSP using the PSP's internal font (firmware pgf files)

Changelog:
* added column printing with automatic linebreaks - no need to worry about overwriting parts of the screen or printing outside the screen anymore (use intraFontPrintColumn())
* added full justification (flush left&right) for column printing (flag INTRAFONT_ALIGN_FULL)
* various optimizations related to UCS2 conversion (thanks to StrmnNrmn)
* added functions to print/measure the first n chars of a string (intraFontPrintEx() and other ...Ex() functions; thanks to StrmnNrmn)
* bug fixed where intraFontMeasureText() could return a wrong value because multi-byte strings (S-JIS and UTF-8) and codepages were not yet properly handled
