Makes the MIUI forums usable for the english, chinese, indian and russian versions.

Note: This script isn't useful since the 8th of April, when the MIUI forums were merged into the Mi Community: http://en.miui.com/thread-6279183-1-1.html

This removes:
* Big medals
* Signatures
* Userdata under the profile
* Experience widget at the end of posts with the ratings
* Profile images
* Reduces margin between comments
* Annoying "Excellent" stamps
