New Locale handling & RageMenu Setting

[Maximus7474]

Locales Changes

1. Altered locale handling to function with SETTINGS.lua, making it easier to switch locale
   • (would of ideally used convars to reduce unnecessary code changes but it's a pain to explain people what a convar is)
2. Added French locale

RageMenu Setting:

1. Added an option to SETTINGS.lua to disable completly the rage menu, benefits:
   • Makes it easier to disable it if a server decides not to use it
   • Reduces client side resource consumption when turned off

I'm open to any discussion or alterations to be done.
