Subject: [PATCH] Fix compile errors due to None redefinition by X11/X.h

X has a #define None 0L, which leads to compile errors when None is used
as an identifier, e.g. enum foo { None, ... };

Move the Xcm.h include to the end so the definition does not affect any
other included headers. Also move the Qcmse class to the implementation
file, so no X11 headers are needed in qcmsevents.h.
