Remove the update button from sheriff-o-matic

This CL removes the update button from sheriff-o-matic. We now automatically
update the view. If you want to update faster, you can reload the page now that
it's fast.

Also, I've cleaned up a bunch of CSS related to the top bar.  We'll likely want
to iterate on this look a bit. I've also removed a bunch of tabs.

Rename some methods by removing 'AfterLayout' postfix

We'll need these methods to invalidate paints even there is no layout.

This change is remaning only, without any change of functionality.

Update GOM to use latest ARB username

I also updated app.yaml to ignore all the *.md files
and other bower_components files we don't actually need
to upload to GAE every time.
