Subject: [PATCH] Support different colors per completion column.

Now colors.completion.fg may be set to a list to specify a different
color for each completion column. For example:

:set colors.completion.fg [black,blue,white] will use black text for the
first column, blue for the second, and white for the third.

Setting to a single value still works and behaves as before. The default
is unchanged from 'white'.

Resolves #1794.
