Allow admins to correct/customize language strings #508
Description
The translation strings are currently only known on the browser side. This means we can't edit them from the PHP/ Crouton Settings Page.
The idea would be to store them on the wordpress side, probably as part of the crouton options storage and to send them to the JS side using wp_add_inline_script. Obviously, users of croutonJS can't edit the translation, they will be stuck with a static JS file, like now.
This would mean that I don't have to worry about tranlations every time a new string is added, or do a new release every time a correction comes. Admins can correct the language themselves and we can collect the changes and do a release when convenient.
