Indentation & highlighting features

There are some differences (features) from standard Vim 7.4 files.

• No line wrapping (textwidth = 0).

• Indent case as follows:

    case x of
      NONE => "none"
    | SOME of str => str
  

• Indent handle as follows:

    call_smth_dangerous
      handle Err1 => 41
           | Err2 => 42
  

• Indent functional pattern matching:

    fun length [] = 0
      | length _::xs = 1 + length xs
  

• Indent let after fun:

    fun double_sum (x, y) =
      let val sum = x + y
      in 2*sum end
  

• Fix indentation of if/then/else when using =.

• Fix highlighting of =>, :=.

• Highlight record fields in type declaration, record creation and record patterns.

These features are also available as independent plugin.
