Eliminate GCC signed/unsigned warnings related to encodings: The

encoding in the RFB protocol has always been signed, and signed values
are also used in the specification (ie DesktopName = -307 etc). In the
code, however, unsigned types were used in a number of places, but not
all, which causes warnings. This patch fixes the problem by switching
to signed values everywhere.
