Subject: [PATCH] Indicate squashing is in progress

When squasher is running the rails app, set an environment variable that
the Rails app can interrogate. This way the rails app can behave
differently while squashing.

For example, to disable any rake tasks (like rails-erd) that might hook
into db:migrate tasks and break squasher.

We use an environment variable here because squasher runs outside the
Rails process. So the Rails app can't reference the Squasher runtime
itself.

fixes #83
