Fixed the menu is now fully translatable! ouf

Fixed javascript handling of translations: we can now load translations strings in several places in the templates, they will all be concatenated into one bigger object
Fixed handling japanese error messages in API with correct charset
Finished (hopefuly?) to make all strings translatable.
Added colored logo now in login screen
All templates now defined the dates necessary to build the calendar, as we notice that most pages want to show the calendar.
Added destructor to LogStats/Db.php so that plugins don't have to call disconnect() on the object
Made JS tag smaller
Improved templates structuring, refactored CSS, etc. still lots to do in this area, if you wanna help?
