Reattached/fixed enh-ruby-forward-sexp, broken when switching to derived-mode.
Rearranged abbrev/syntax/keymap sections to mimic idiomatic derived
modes. Should fix some of the key bindings, at the least.
Added some of the more generic keybindings from ruby-mode while I was in there.
Removed skip-syntax-forward from enh-ruby-forward-sexp. Fixes #51.
Fixes #9.
