Support Environment Isolation

[joshperry]

Errors are generated when trying to enable environment isolation while using this module.

$ puppet generate types --environment pgproxy_update
Error: /srv/puppetmaster/current/environments/pgproxy_update/modules/rvm/lib/puppet/type/rvm_gem.rb: title patterns that use procs are not supported.
Error: /srv/puppetmaster/current/environments/pgproxy_update/modules/rvm/lib/puppet/type/rvm_gemset.rb: title patterns that use procs are not supported.

I'm attempting this change, similar to https://github.com/puppetlabs/puppetlabs-java_ks/commit/3526d1c0a0f7026ac0821faf08912506d3be8d11
