Rebuild with Colortemplate v2.2.0.

Fix an error about s:termtrans not being defined. The error is due to
the new way Colortemplate generates the output code.

Make g:solarized_extra_hi_groups=1 by default, as the Vim issue with
filetype-specific highlight groups in color schemes has been fixed a
while ago.
