HT Editor XBE Support

This is the very first beta version of XBE support
within HT Editor. This is more or less only a preview
of what will hopefully soon be part of the official
HT Editor package. Right now you can view the header,
the imports and a disassembly of the XBE file.

Some features are just quick hacks and therefore could
be crashed by malformed XBE files for now. This will
be cleaned up soon.

	1) Make entrypoint/thunk address editable without
	   by hand xoring
	2) ... your ideas ...

If you find any bugs related to the XBE support of
have a nice idea for the XBE support just contact me
