Changed the clipboard API so that it will work with X

Browse Source 
In X, clipboard/selection data is specific to each window, and it
may take some time before the clipboard data is fully transferred.
This actually makes sense because there can be entire images in
the clipboard and it is important the clipboard API supports large
file transfer. Because of this, the Copy and Paste methods have
been moved into Window, and Paste now returns a channel.
