Worked around bogus key mapping on 95/98/me where multiple virtual 

keys are mapped to the same button.  For example, the backslash
virtual key shares a button with some other virtual key on british
english key mappings.  Synergy could end up using the wrong virtual
key.  In the given case, the other virtual key produced no character
at all.  To determine which virtual key should really be mapped to
a button we map the button back to a virtual key and see if it's the
virtual key we started with.

Also fixed mapping of pause key.  Previously, windows+pause sent to
a win32 client wouldn't bring up system properties like it should.
