Fix fontpatcher to set proper width on new glyphs

Gvim on Windows seems to only considers a font to be monospaced if every glyph
has the same width; this setting appears to be unrelated to the glyph's
bounding box.
Allow fontpatcher to output TrueType fonts

Many TrueType fonts look like garbage if they are converted to PostScript
outlines. This change allows TrueType fonts to be generated back as TrueType
while any other format will be generated as OpenType.

Update font patcher

This commit introduces some changes to how the font metrics are
calculated as well as various fixes for glyph alignment and overlap. The
update uses the Latin Extended-A and Box Drawing glyphs to determine the
largest glyphs, this seems to be a quite reliable way of determining
both the glyph height and the maximum width.

An overlap property has been added to SYM_ATTR, the glyphs will be moved
`font.em / 48` in the direction of the glyph alignment so it overlaps
with the previous/next glyph. This is necessary for the block arrows so
no gaps occur.
