Some fixes for receiving files via {x,y,z}modem:

- let transfer dialog reset progress bar when finished
- typo: s/Sent/Received in received confirmation dialog
- specify filename for xmodem (the man page is not very clear about this, but
  it doesn't work without filename!)
- add --overwrite

Here's the big problem:
For user security, I'd rather use --rename than --overwrite (or make it
configurable).
But:
 * --rename is not supported at all by rx/rz/...
 * --overwrite is not supported by ymodem
 * --overwrite is always used by xmodem even if not used

I want to kick the authors of rz now...
Anybody knows a solution?
