* Lots of improvements to code

* Reversed some stuff. Thanks API 16

* Code fixes

* Performance improvements

* Moved adapter creation to constructor

* Small changes

* Removed sources settings from settings menu. Added OnChangeListener in catalogue. Made setting icon visible if room.

* bug fix

* Code review part uno

* Code review part uno-2

* Single recycler approach

* Add last source used

* Fix scroll state and some layout issues

* Fix wrong item binding

* Use data class for items

* Calculate item position and count while binding

* Fix background color with slices

* Reuse slices. Fix card background. Flatten constraint layout
