Fix to stop xwinclip from clobbering remote clipboard

[Kensuke Matsuzaki]

Øyvind,

The reason why non-text clipboard contents is lost is not that.
To know windows clipboard change or not, you can use
SetClipboardViewer and WM_DRAWCLIPBOARD.

xwinclip clime CLIPBOARD ownership, but xwinclip can handle only XA_STRING,
UTF8_STRING and COMPOUND_TEXT.
xwinclip must hold all target to avoid clobbering X clipboard contents.

GNOME Clipboard Manager seems to do those well.
Perhaps their documents and code will help you.

By the way, latest code is here.
