Title: ignore some more runy management files

it has become more standard that RVM now recommends using a non-`.rvmrc` file, and other ruby managers seem to follow convention of using the `.ruby-version` notation for the ruby binary selection.
rvm adds the use of `.ruby-gemset` for gemset selection.
