Funky meta-data name for upper case property

If for some reason you have a getter in all upper case, the generated lower-case counter part does not look right: getFOOBAR() becomes f-o-o-b-a-r

@philwebb if you have a better idea, please let me know. I am not a regex super-hero so I may be missing something (ping @sdeleuze, @dsyer)
