Add option to colour matching portion of results.

This was done by breaking the selected result into three parts, and
rendering each separately. A side-effect is that ligatures split when a
match ends inside them, but I think that's the correct behaviour (rather
than highlighting the whole ligature).

There may be issues with some non-latin languages that make much more
extensive use of ligatures / combining characters, however.
