Fixed several win32 bugs. First, synergy wasn't forwarding mouse

events to other hook functions, which broke some tools like objectbar.
Second, windows key processing was fixed.  Previously pressing and
release the key would only send a press event, locking the user onto
the client window;  also, the win32 server treated as a Meta modifier
instead of a Super modifier, which broke any use of it as any kind of
modifier key.  Third, added hacks to support several key combinations
on windows 95/98/me that are treated specially by windows, including
Alt+Tab, Alt+Shift+Tab, Alt+Esc, Alt+Shift+Esc, Ctrl+Esc, and any
combination using the windows key like Win+E and Win+F but not
Ctrl+Alt+Del.  Fourth, scroll lock only locking to the client (which
only happened when using a synergy server on windows) has been fixed;
unfortunately the solution causes a lot of screen redraws for some
reason.  Finally, there's been a fix to clipboard handling that may
or may not fix a problem where the clipboard would stop transferring
between systems after a little while.  I can't be sure if it fixes
the problem because I can't reproduce the problem.
