Rename Repo/Project

[LunNova]

We've been boring and called the project "Vuzii" - maybe we should give it a proper name instead of copying the challenge host's name?

Someone ( @iliawnek or @Masonator117 ?) suggested "Trendr" earlier.

Trendr is already a thing but +1 for rename

Renaming to "Trenderer" for now after @iliawnek's joke suggestion in discord. We can change it to something more sensible later, but for now it's quite important not to be using the same name as Vuzii which could cause confusion.
