* Need to move addons-server install from "deps" to "commands" because
editable mode is not compitable with hash-checking mode for "pip install"
* Need to add extra install commands for anything used to depend on
"compiled.txt" or "prod.txt" because the two have been splitted into
with and without hash files.
* Adds simple wrapper around addons-linter
* runs addons-linter if switch 'addons-linter' is active
* only runs it for WebExtensions
* Adds basic compatibility wrapper to integrate it's output
into the rest of AMO without rewriting everything

This reverts commit 81d6f202ee.
django-cache-machine==0.8 does not match what we were using in the git
revision beforehand. This is blocking us on master so I'm just going to revert
temporarily while we fix up pyrepo to get the right packages on there.
