more font improvements and cleanup

Get rid of the notion of a font's "ascent"; the reference point for
drawing is the top-left corner of the character box rather than the
baseline.  Add some more space between the menu entries and make the
highlight bar around the text.

Replace the default font.png with two images; the build system will
include one or the other based on the resolutions of the device.

Restore the original compiled-in bitmap font, to fall back on when
font.png can't be found (eg, in the charger binary).

Add support for bold text (when a font.png image is used).

+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
