Add limited unicode support

If we encounter a utf8 sequence corresponding to a glyph for which a
known XKB compose sequence exists, we replace the glyph with the
corresponding sequence. This allows non-english users to easilly specify
alternate glyphs without having to memorize the appropriate macros.

v2.3.0-rc

This is a major release which breaks backward compatibility for
non-trivial configs. (we are still in beta after all :P).

In the absence of too much blowback this will probably become the final
v2 design.

Much of this harkens back to the v1, with some additional simplifications
and enhancements.

See DESIGN.md for a more detailed account.
