lukas e3ff4b58c6 provide plugin for rbfu the ruby version switcher
Evaluates $(rbfu --init --auto) if rbfu is installed on the system,
also has a custom rbfu-rubies method which lists the installed
rubies which are available to rbfu.

For compatibility with themes, also creates the rvm_prompt_info
function, so existing themes should work out of the box.
