Based `Internet.hs` on Wreq

- And thus have moved off of http-conduit.
Initial conversion to `aur` library

- Cut out big swaths of old code
Use `Traversable.mapM` for cleaner IO/Maybe interaction
`A.hs` conflicts fixed

- There is _far_ to make conversion between String and Text going
  on in there. All of Aura should probably be converted to Text.
Removed copy of `Network.HTTP`

- With the introduction of wreq it's no longer needed.
Merge pull request #262 from aurapm/wreq

Moving to `aur` package for AUR interaction
