- #2841479 by alex.designworks: Fixed profile preferences and plugin version are not reverted from features

This includes two larger changes, the first one being profiles now record the
editor library version they are compatible with. This allows for better control
when moving from one library version to another. The second change is to the
profile overview UI, which now only stores profiles temporarily until they have
been explicitly saved.

This change also includes a new method of retrieving the list of stylesheets
added by the selected theme, and a new alter hook for that list.
If CSS aggregation is enabled the final list of stylesheets sent to the editor
will also be aggregated/optimized if possible.
