3.0.0 wip

Hey guys do not have the unit test updated yet... I need to add more tests but this is for your consideration:

1) needs to have change fired on blur - ADDED
2) support unit values ('px', 'em', etc) - ADDED
3) return consistent values on change (integer vs string?) - RETURN STRING IF UNITS ADDED INT IF NO UNITS
4) no min max restrictions when manually entering - NOT ADDED 


Try it out see what you think
