[aur-general] small AUR cleanup

[Kevin Vesga]

Please delete these four packages. Xyne has removed their source and
bauerbill/powerpill likely wouldn't work with the latest pacman anyways.

[1] bauerbill - https://aur.archlinux.org/packages.php?ID=52251
[2] perl-xyne-arch - https://aur.archlinux.org/packages.php?ID=52252
[3] perl-xyne-common - https://aur.archlinux.org/packages.php?ID=52253
[4] powerpill - https://aur.archlinux.org/packages.php?ID=52254

Please delete geany-colorschemes [5] as it has been superseded by
geany-themes [6].

[5] https://aur.archlinux.org/packages.php?ID=35555
[6] https://aur.archlinux.org/packages.php?ID=53889

Please merge qutim [7] into qutim-stable [8].

Please delete aim [9] as the source is gone.
