[aur-dev] archweb branch merged into master

Hi, guys! This turned out to take much longer than expected, but the archweb branch (>50 patches, that is) has finally been merged into master. There's a few things that still need some fine tuning but it basically pretty much looks like archweb already. Special thanks fly out to canyonknight, who contributed several patches and helped a lot with merging our work together! Cheers, Lukas
