Language implementation

[datmw]

Hey there,

I just tried to set up a new language in UserPie and stumbled upon a type in a variable.
$language is written as $langauge in config.php in lines 34 and 36, but in the condition in line 34 it's written correctly causing the issue. It's also written wrong somewhere around line 22 in settings.php.
Hope you could fix it in the next version, so future international users won't have that problem.
Please let me know if you are interested to include a German translation at some point.
By the way, would be nice if you could include localisation subdirs for the email templates, too.

Greetings from Germany,
