Feature request: initiate file transfer from clipboard (paste)

[brentkearney]

I'd like to migrate users from Trillian (MacOS), but one productive feature they would miss is the ability to paste screenshots into the chat, and have them automatically transfer. Having to save them to file first, then drag and drop the file and click Send adds a few steps. Especially for those who have their Desktops polluted with thousands of files ;).
