Implement extended UCI info string variant option

To allow UCI engines to also define variants with different board size
and parent variant, an extended version of the info-string-variant command
is recognized. This can also incluse 'files', 'ranks', 'pocket' and
'template' fields. The default values for these are 8, 8, 0 and "fairy",
so that we remain compatible with the old info-string-variant command when
the new fields are absent.
