[Twisted-Python] patch for protocols.telnet.Telnet

[Jeremy Noetzelman]

There's a bug in the telnet protocol, which will only process one 'line'
per call to processChunk().  This is buggy, because if you send a large
amount of data to a connection, such as via copy/paste, it will only
process the first two lines of it, and you're stuck mashing the enter key
to get it to process the rest.

Patch makes it process all lines instead of just one.
