Spoike c0680334c7 What could possibly go wrong?...
Multiple consoles can now be printed/cleared via extra con commands.
Fixed the tab-completion alignment, by adding support for \t characters.
Changing the download mechanisms. Don't try downloading an ftp:// file. It'll probably crash you for now.
Trying to fix load time issues on q3bsps with a lot of curves.
Fixed sprites.
Added warning prints/spam where the new backend is bypassed, thus marking things that still need to be fixed.
QTV proxy fixed to not sit on qw servers unless someone is actually watching. Will ping for status requests still.
QTV proxy now supports ipv6.
QTV proxy now attempts to use the fte browser plugin.
Reworked the browser plugin code, now uses threads instead of ugly hacks. This should make cooperation with other such plugins work. Fixes unresponsiveness of opera, and gives an API that can be used from any other bit of software you want, tbh (read: internet explorer/activex plugins).
