A new plugin called "exec" has been added, with command /exec.

The command /exec can execute external commands and display output in WeeChat.

It is similar to /shell (script shell.py), with major improvements:

• run many commands at once,
• send signals to commands,
• send data on stdin of a command,
• line numbers in output,
• ANSI color support,
• command timeout.

Other features coming soon: pipe output to WeeChat command or hsignal (to use in a trigger).
