Propose and apply a scheme for localization keys

[chezzdev]

Description

It's easier to navigate and come up with names for the new localization keys, when the appropriate scheme is defined.

Goal

Propose the following naming scheme:
(context where the key is used, typically the name of the screen, or General if used in multiple cases)(type of element e.g. title / body / button, may be omitted if key is used in different elements)(specification if there's more than one instances of that type).

Examples:

General_Button_Cancel (used in several places)
General_TermsOfService (used as a link substring and button title)
Welcome_Title (title of the welcome screen, it's unique so no need of specification)
Menu_Button_Segmentation (similar elements are easy to search with autocomplete)
Menu_Button_Detection

Steps

• Agree on the format
• Apply the format
