enh-ruby-mode's highlighter breaks when the buffer is unexpectedly
reverted. This sacrifices its superior highlighting and indentation, but
was too much trouble to maintain.
The +rails flag sets up projectile-rails as a minor mode for
enh-ruby-mode and, if enabled under :lang, web-mode. Projectile-rails
keybindings are under "<localleader> r".
robe-rails-refresh was moved to "<localleader> R".
+ Robe is now to be started manually.
+ Adds more keybindings for robe (including <localleader> ' for
robe-start).
+ Use ruby-mode if ruby isn't available (e.g. editing ruby files on
remote systems), enh-ruby-mode otherwise.
+ Added rake, bundler, rvm, rbenv and minitest packages
+ Added $RBENV_ROOT/shims to exec-path. This should fix rbenv support
for the ruby version display in the modeline.
