Editor inline docs: show long types and fix operator doc links

Hi Evan,

here are two small patches to the inline docs

1) Wrap long types when showing detailed documentation (option C as discussed here https://groups.google.com/d/msg/elm-discuss/_xmbeVfjYbI/8diPbbsvbRUJ)

2) Fix anchor links for operators that need '(' ')' wrapping.
