Overview all badges network wide

[Alex1607]

Add a new page which shows an overview of all the badges there currently are.
It should look something like this, courtesy of xadq

Paging is optional for the first version as the API doesn't offer it anyway, and there are well below 100 badges.
The API endpoint for this is: https://api.greev.eu/v2/badge/all.
As for showing it in the displaying of it on the start page, we can just add it to the misc category.

And here image for the button on the start page
