Fix test failures, that did occur because of missing previously used `reload_status!` call
Use state machine for pipeline event processing
Upgrade Rails to 4.2.7.1 for security fixes.
Update gitlab-shell to v3.3.3

...
This change simplifies a Pipeline processing by introducing a special new status: created.
This status is used for all builds that are created for a pipeline.
We are then processing next stages and queueing some of the builds (created -> pending) or skipping them (created -> skipped).
This makes it possible to simplify and solve a few ordering problems with how previously builds were scheduled.
This also allows us to visualise a full pipeline (with created builds).
This also removes an after_touch used for updating a pipeline state parameters.
Right now in various places we explicitly call a reload_status! on pipeline to force it to be updated and saved.
