Basic localization setup (only partial solution) and language selector menu

I did some work on localization, based on Laravel's $language, and $languages application config variables, and its built in url solution (automatic language setup based on url, like domain.com/en/).
1. set up basic languages files (language/en/administrator.php, plus two languages: de, hu)
2. changed view files to use these language lines (most places)
3. integrated language selector menu in main menu. It only shows up, if $languages array is not empty.
4. validation works out of the box

TODOs:
1. "x characters left" function (we need to send a template to knockout, not just the number of characters)
2. in filter model, the from-to version
  a) maybe the best is to change "to" to a symbol "-", so no localization is needed
  b) a universal grammatical solution wold be: "pre-text X middle-text Y post-text", so in English it would be "from X to Y", but different in other languages (like in Hungarian, "X től Y ig"). Its bit messy, i suggest a)
3. Exception messages
4. Send proper language texts to knockout, mostly messages and alerts. 
5. Set up plupload (it already contains lang files)
6. Set up ckeditor (original project contains lang files)
7. Set up timepicker
8. Set up design and own styles for language menu
9. Uploaded image doesn't show on page, because using languages alter the uri, adds the country word (en) to it (right after public). It causes no bug elsewhere, but here. I didn't find any nice solution, probably a cautious strreplace will do)
