Add Xft font rendering support
Change default font to Bitstream Vera Sans Mono-8
Use fallback font when character is missing from main xft font
Support multiple fallback fonts (up to 4)
Fixed bug where it defaults to last font found
Add full UTF-8 support for Xft
Small code cleanup (redundant couple of lines)
Cache the xft font width; XftTextExtents32 leaks?
Fixed wrong font being selected for characters
Destroy the xft drawable object every input (memory leaks?)
`screen` variable naming conflict
Early return causes leak (xft drawable not destroyed!)
