Support prefixing different binaries with different ruby versions
For example
set :rvm_ruby_version, 'ruby-2.0.0-p481'
# eye, a process manager, runs with ruby-2.2.0
# clockwork can run with the configured ruby version ruby-2.0.0-p481
set :rvm_map_bins, fetch(:rvm_map_bins, []).push(['eye', 'ruby-2.2.0'], 'clockwork')
