Subject: Added options to DocParser.

So far only 'time' is supported.
'time' now gives a breakdown of block parsing, inline parsing,
and rendering.

Currently the ratio is

block parsing: 725ms
inline parsing: 332ms
rendering: 213ms

so perhaps block.js is the best place to look for further optimizations.
