improve colors for rust/solarized

Browse Source 
* bring colors more aligned with upstream solarized implementations
  (e.g. vim, emacs)
* tweak rust syntax
    * add more details, like operators, highlighting certain traits and
      types from std, etc
    * remove certain highlighters, like user types. This has the effect
      of just highlighting almost the whole code base one color, and
      wasn't really correct either. CamelCase for types is only convention
