Saving the post content using localstorage

Browse source 
If a post is created and the browser window crashes or the Composer window is hard-closed in some other way, all content is lost. Content is now saved temporarily so that it can be displayed again when the browser is restarted.

The content in the localstorage is discarded after 10 minutes after the editor has been exited.

The system now checks whether the editor field is filled. If there are no characters, there is no reload check.
