sublimeREPL_rbenv_changes

1. Go to your sublime home directory, then Packages/SublimeREPL/config/
2. Open 'Ruby' directory in config, make the changes in this PR to pry_repl.rb
      https://github.com/wuub/SublimeREPL/pull/372/files
3. Run 'which ruby' in your terminal, and copy the path it returns.
      eg. /Users/sudhagarsachin/.rbenv/shims/ruby
4. In Main.sublime-menu, line 33, the "osx" to this JSON.
        "osx": [
          "/Users/sudhagarsachin/.rbenv/shims/ruby",     // replace this with your path
          "${packages}/SublimeREPL/config/Ruby/pry_repl.rb",
          "$editor"
        ]
5. Now open the Rails directory and do the same changes 
   in pry_repl.rb and Main.sublime-menu
