up2k: tristate option for overwriting files; closes #139

adds a third possible value for the `replace` property in handshakes:

* absent or False: never overwrite an existing file on the server,
   and instead generate a new filename to avoid collision

* True: always overwrite existing files on the server

* "mt": only overwrite if client's last-modified is more recent
   (this is the new option)

the new UI button toggles between all three options,
defaulting to never-overwrite
