Fixing the adjust font restore scroll and adding unit tests
Fixes after first review
Merge remote-tracking branch 'upstream/master' into tom/font-size-2
Changes to the restore scroll
Allow Quick Open plugins to specify both fileTypes and languageIds to
remain backwards compatible with older Brackets builds (prefer languageIds
and don't issue deprecation warnings).

Also, clean up mis-capitalized var name.
