Title: Add rbfu prompt support

`rbfu` is a simple alternative to rbenv and RVM (ie., it manages and switches between installed Ruby versions). This pull request adds support for displaying the Ruby version currently activated through rbfu in your prompt (which is as simple as displaying the contents of the `$(RBFU_RUBY_VERSION)` variable).

I have also introduced a new function named `ruby_version_prompt`, wrapping the various methods available.
