Submitted to the AUR

Hi!

Just thought I'd let you know that I created an AUR package to help spread this software around. I recently stumbled upon it and I'm a big fan; I can clearly see a lot of love went into this! Here's a link to the AUR package: https://aur.archlinux.org/packages/cobib/. Let me know if there's anything I should change in the PKGBUILD! I'm pretty new to making AUR packages myself.
