Enables shelling out from a ruby process started with rbenv to a ruby process with a different RBENV_VERSION. Fixes #121 This removes the workaround created for #15 and solves `ruby -S` support by setting RUBYPATH. PATH is never changed. To illustrate how RUBYPATH changes in various configurations: PATH=~/bin:~/.rbenv/shims:/usr/bin:/bin RBENV_VERSION=1.8 ruby -S rake #=> executes ~/.rbenv/versions/1.8/bin/rake #=> RUBYPATH=~/bin:~/.rbenv/versions/1.8/bin:/usr/bin:/bin RBENV_VERSION=2.0 ruby -S rake #=> executes ~/.rbenv/versions/2.0/bin/rake #=> RUBYPATH=~/bin:~/.rbenv/versions/2.0/bin:/usr/bin:/bin RBENV_VERSION=system ruby -S rake #=> executes /usr/bin/rake #=> RUBYPATH=~/bin:/rbenv_shims_were_here:/usr/bin:/bin RBENV_VERSION=1.8 ruby -S rake #=> executes ~/.rbenv/versions/1.8/bin/rake #=> RUBYPATH=~/bin:~/.rbenv/versions/1.8/bin:/usr/bin:/bin
