Missing Functionality in GetSimple 3.0 - for Plugins

[mvlcek]

on the setting page a setting for the frontend language ...

Surely, this should be the job of the language declaration in the page header?

Given that most installations don't have the language declaration changed from the default, I can see a case for setting the language in the backend and adding it to the headers (with get_header()).

The important part is that a plugin must be able to find out the language to output texts in the correct language. I'm open for any suggestions that make this possible.
