file copy&paste using webdav
First of all, I know neither C++ nor the Windows APIs well, so any suggestions are really welcome :)
In comparison to the linux vdagent, the situation seems to be less complicated. We don't need to handle different targets as CF_HDROP seems to be enough and spice webdav service already does the mapping of the network share to a local drive, so the vdagent just needs to find it.
A minor issue is, that the folder with clipboard data, currently named .spice-clipboard, is not hidden. If Windows asked for this property, it could be implemented in phodav, but that needs to be checked. Anyway, probably not a big deal.
