Added the ability to change the rating from Like to Dislike and vice versa without having to "undo" the rating beforehand.
Fixed Likes/Dislikes counters not being incremented/decremented (it previously required to go back and then re-open the video page to see the change).
Improved overall code performance and readability by removing redundant calls.
Fixed some typos in comments
Removed "video_rating_none", "video_rating_like" and "video_rating_dislike" from strings.xml as they were not translatable and only used in the code without ever being displayed to the user. No longer the case due to changes upstream in the develop branch.
