Switch to using a repository & facade for Redirect, add eloquent support

[ryanmitchell]

This PR adds eloquent support to the redirects.

To do this I've:

• Moved any calls to Data\Redirect to a facade (Facades\Redirect)
• Created a repository contract and query builder contract
• Created a stache repository and moved the save/delete/query/find methods from Data\Redirect to it
• Created eloquent repositories

Let me know if you need/want anything else to have this approved.

Closes #106
