Added locale helpers in terms of keyboard language/layout. archinstall.list_keyboard_languages(), archinstall.search_keyboard_layout() and archinstall.set_keyboard_language() work together to help listing, finding and setting a keyboard layout in terminals. Won't work for X-frontends, but will do for CLI installation methods. Added a language selector-helper-function with a crude search functionality. Added all this to the guided template.
