pacman: Simplify support for AUR helpers

There are a number of things happening here.

- Extra support for yaourt has been removed
- Docs have been updated to explicitly call out that AUR helpers are not
  officially supported
- aurutils has been suggested to make common operations easier
- A utility function called aurget (similar to aurfetch from aurutils)
  has been added to make cloning AUR repos easier.

Fixes #1531
