Message:

Jabber file transfer now also with sending! You can't use a proxy yet when
sending, that's my next task. You can use proxies when receiving though!

I also changed the buffering strategy. Previously receiving continued till some
buffer limit was reached, now only one message is received and receiving stops
till it is delivered. This keeps the buffering space per file transfer to a
minimum(currently 4k). Makes sense when used on a public server. For public
servers a throughput maximum would also be interesting...
