weechat script DoS

hello ~teammates,

it was discovered today that the apply_corrections.py weechat script is a denial of service attack vector via a naive regex implementation.

cpu load spiked as everyone's weechat instance choked on a massive regex. i intervened by killing all affected weechat instances. if your weechat died, this is why.

i've also removed apply_corrections.py from the new user configs.

please remove apply_corrections.py when you log in and start weechat back up. to do this, you can remove the script itself from ~/.weechat/python or run /script remove apply_corrections.py directly inside weechat.

thanks, ~ben
