Added the following scripts:
* Lithuanian (thanks to petraszd for the patch)
* Serbian (thanks to offy)
* Azerbajani (thanks to Ali Ismayilov)
Fixed the following issues:
* In Polish character map, some uppercase letters were
converted to a lowercase ascii equivalent.
* The letter Y with a diaeresis had a lowercase version but no uppercase.
The code was also simplified and cleaned up:
* Use of `var` statements everywhere
* Systematic use of semicolons
* Proper looping over arrays and objects.
Thanks to @oinopion for his help in getting the javascript
into proper shape.
Fixes#8561, #11035.
