Add sorting by most unique reactions

[Arashfa0301]

Add sorting by most unique reactions. So in the example below, the lower quote would come first in the list.

I'm not sure I understand this issue correctly.
In your example, both quotes have exactly 42 reactions.
Is it:

• A: About sorting on the "variation of emoji types"?
• B: About sorting on how many different users have reacted on a quote?

@danielyanghansen He means unique user reaction, so B. I think unique users says more about a quote than amount of reactions.
