X-Chat 2 Shell Plugin

I wrote a X-Chat 2 Python Plugin today that allows you to run commands in a shell.

You can split a command you want to run into multiple lines by ending your input with a \ — just like you would do in a terminal. Newlines can be done using \n though this is currently the only workingescape sequence. Your input is passed to bash in a thread so that X-Chat doesn't freeze. I even got multiple ncat instances connected to a `ncat --chat` inside different channels. See for yourself, here's the sourcecode. If you got questions feel free to ask.

Edit: Fixed the case when there was an empty line the output stops, now it just doesn't print empty lines.
