[HACK] moved the creation of SharedProject into the
SharedResourceManager

This is currently the easiest way to get rid of the SharedProject
reference in the ISarosSession interface. As the SharedProject class
also references VCS stuff which references Eclipse Subsclipse stuff this
is hardly to convert.

And again, this class is a dead left over when partial sharing was
introduced, only containing methods for logging and VCS stuff.
