Make the feed connected to the database and thus accordingly growing, making it dynamical

[2Tricky4u]

I would like to load feed and user details profile image from the database and make it expand as the user scroll through it.
Also lazy loading.

The files I think I will work with the most is:

UserPhotoFragment.kt
UserPhotosViewAdapter.kt
ProfileDetailsFragment.kt
A file for firebase (need to ask Luca)

Note to myself: Look at paging library

Also add the ability to add a user to his followings
