QMessageBox overhaul: unify buttons, style and appearance of info dialogs, fixing a few typos and return values along the way

add standard copyright header

don't try to delete a default scheme

Completely arbitrary tweaking of tunnel values (avoids a nil) - still needs smooth curves (probably a target dx/dy to aim for, and slow alterations) and taking less CPU. Also disable unused function in Highlander

- Fix desyncs triggered by AI - Assert for valid input in /timer and /setweap

Check cake and air attack again if walked far from initial position (not tested)

Track targets better in multiattack mode

Mark places where tried to jump, avoid too much of thinking

*sigh* revert the multishoot thingy. worked fine in my tests w/ smine and cleaver, screwed up deagle. need to find out why, but sleepy. for later

Someone should look this over to make sure it should stay in

Disable jiggling of cleavers 'cause it just looks odd. Adding a constraint based on proximity to portal is an option too, this was just easier.

Turn off freezing in multishoot, unless unc0rr can come up w/ a good reason why this was here :)
