This is my first pass at where we should be marking the main launch/startup moments in FTU, plus minimal refactoring to facilitate that. There's a marionette test in there to sanity check the result.

I like the 'languageready' mark, as it's taking a really long time lately to load and show the available languages.

Also, treeherder seems to be angry today, lots of tests failing, so probably needs a new push.

Rebased and pushed, treeherder looking much happier.
