[Feature] Backlight settings (#137)

* Added backlight settings

* Changed location of the brightness setting

* Fix row size of brightness settings

* [apps/settings/brightness] Update translations

* Fix dimmer

* Update translations

* [apps/settings] Add dimmer duration setting

* [apps/settings] Ensure of the brightness level is greater than the dimmed brightness level

* Make transition smooth

* Removed transition time setting
I personally think that this setting is completely useless except if you absolutely want a transition that is not smooth, which is weird.

* Moved everything related to brightness in one submenu

* Some refactoring

* Update defaults

* Removed unnecessary translation

* [apps/settings] Fix Shift + Minus/Plus in settings

* Apply suggestions from code review

* [apps/shared] Remove a think that I don't know what it is

* Apply review suggestions
