[aur-general] Adopt Monkeysphere

[Jeremy Audet]

Some small suggestions:

* I'd suggest quoting the first item in the `source` array, on line 14. The
variables being interpolated into that string should never contain spaces
or other undesirable characters, but why take a chance?
* Lines 15-17 contain tab characters. I'd suggest replacing them with
whitespace. That helps people like me who make tabs display as four spaces
by default, not eight.

Those changes have no functional impact at this time, so if you choose to
make them, you can just upload a tweaked pkgbuild without bumping `pkgrel`.
