#13 Adding Sipe For Microsoft Office Communicator

[Dave Villeneuve]

Having Sipe added would allow pidgin on the Mac to support using Microsoft Office Communicator. We have it for Pidgin on Linux and Windows, but missing in MacOS X (unless one downloads and builds all the packages via Fink and runs it under X11).

Then we would have a single on all platform solution for IM in the Enterprise.

BTW, sipe seems to come configured to make warnings become errors ... I had to tweak the makefiles.
