clean up LoadImage and UserPathz/AltPath/etc related redundancy by introducing 3 new functions in uStore.pas

* don't build moc for campaign.h * added campaign.{h,cpp} to hedgewars.pro

oops

use old approach for printing gl extentions for pas2c (less complex/no StrUtils dependencies)

min -> qMin

don't query/print GL_AUX_BUFFERS if video recording is disabled

print all GL_EXTENSIONS properly to logfile (should a;sp fix build on systems with compiler/lib versions that can't implicity cast PGLubyte to PChar)

Allow adjusting bitrate so that I can get a somewhat usable webm video. The audio is still tinny and unlistenable. Configuration option for that might be helpful, or just adjusting defaults in the wrapper.

add 'a classic fairytale' campaign to cmake install

dos2unix newline fixes on 7 (video recording-)merged files

Move some options to the second page so first page doesn't look ugly on low resolution

neglected stuff

Checking merge against latest trunk

preliminary creeper (not yet functional)

new grave: dragonball (incl. svg) by Randy

tiny (probably) optimisation

A few more operators. Committing in case unc0rr wants to fiddle.

isZero appears to be never used. Use it in a few obvious cases and add web variant.

Fix library installation in win32

disable snowball damage, by request of sheepluva

remove a redundant assignment; whitespace fixes

This should work better

fix build for me

Make ffmpeg optional for frontend

Small fix

Merge Stepik-777's video recording gsoc project

Starting to rewrite uFloat routines to avoid QWordValue - in the interests of JS which may get uint64/int64 in the spec in the future but does not have it now.
