Better NimoTV par Gabriel Duarte

This aims to increase the overall experience while browsing NimoTV, adding features such as:

* Hide the spam of "User has entered chat"
* Improve royal messages readability, by making the text brighter, and more distinguishable from the background
* Hide the gift box popover that appears every time someone donates something like the egg. You can still collect the gift boxes, so don't worry!
