Edit History Log

Description:
Allows you to log all edits made to posts.

Features:
Whenever a post is edited (either in quick edit or full edit mode), the original text is saved and can be viewed by moderators or administrators (exact viewing permission may be set in settings).
The post can be compared to the current post (to see precisely what was changed).
The post can be reverted to an earlier version (exact revert permission may be set in settings).
The number of times a post has been edited can be shown with the 'edited by' message (can be disabled; 'edited by' messages must be enabled).
Full language support.
