Add upload of game to ICS for examining

New item "Upload to Examin" in Action menu, calls UploadGameEvent().
Use SAN moves to upload game to ICS, rather than long algebraic
(The ICS did not understand long-algebraic promotion moves)
Use bsetup within examine to set position onFICS, and also variant.
Castling rights do not work yet for FRC. Totally different set of
commands are needed on FICS and ICC.
 FICS does not understand w23 or wild/23, but needs 'crazyhouse' in the
besetup command that specifies the variant. XBoard variant names are
used, except for fischerandom, which is 'fr'. Things like nocastle will
probably still not work.
