Uniform naming of variables and folder structure

[antonykamp]

The naming of some variables isn't uniform. For example, The names of a comment on a list are "comment" and "specialWish". The pages' name with the lists accepted by a user is "accepted list" and "active list". Please take care of other doppelgangers too :)

It would be great if somebody could rearrange the folder structure too. Take the folder "auth" as an example (auth/components, auth/pages, auth/queries, auth/mutations). (done by #52 )

Additionally, it would be great if somebody could change the file-type from "*.tsx" to "*ts" of mutations and queries <3

AND (:D) if it would be awesome if we would use number instead of Number...at the moment, we don't use them uniformly.

Furthermore, we should work with the .ts and .tsx files as intended.
