cleanup: split uiLanguage() in two functions

The uiLanguage() function was used for two purposes: to initialize
the language related preferences and to read the current language.
To make things more easy to follow, split this function in two:
one for initializing, one for getting the current language.

Moreover, don't return the current locale in an out-parameter
as there is already a function to do that [getLocale()].
