Improve 'Save Changes' panel with persisted options or a "select all" option.

The new "Save Changes" options give the end user much more control over how a theme is saved and finally exported. To help serve most users in the best possible way, some items are not selected by default:

On the other hand, some users will want these options on every save. Should we consider adding a "select all" checkbox for these options to save some clicks here?

I think we might also want to consider persisting those selections instead. More than regularly selecting all of them, I think users will probably most often have a preferred collection of options (always save all, never localize text, always localize images, never remove navigation refs).

Right now we give them the same starting point every time.

Yeah agreed, I thought this might be a good way to handle this too.
