* [keymap] adding my Levinson keymap
pretty self explanatory, added the readme, just in case
tested it just now, seems to work fine for my needs
* Update keymap.c
removing the deprecated persistent layer function as Drashna kindly reminded me
* Apply suggestions from code review
incorporated the suggestions, and thanks again for taking care of me with my silly changes :)
