Support for neo2 keyboard layout

Browse source 
Modify aux/kbdfs to work with neo2 layout.
- add new modifier, increase limit on layers.
- Add Kaltgr for mod3
- Add mod4

This change only implements the alphanumeric
block of the keyboard in the kbmap, as neo2
is mainly used for blind typing and is not
needed that much anywhere else, this leaves
the numpad like it is.

(Thanks, jstsmthrgk@jstsmthrgk.eu)
