[aur-general] AUR upgraded to 2.1.0

[Lukas Fleischer]

The official Arch Linux AUR setup has been upgraded to 2.1.0. For a
short list of changes, read [1].

Note that .AURINFO files can now be included in source packages to
overwrite specific PKGBUILD fields. .AURINFO files are parsed line by
line. The syntax for each line is "key = value", where key is any of the
following field names:

* pkgname
* pkgver
* pkgdesc
* url
* license
* depend

Check [1] and the Git log for details.

Please report any issues to the AUR bug tracker [2].
