Much more efficient unfilterJSON() implementation.

Large text messages (e.g. 900 KB message for the horde cvs -> git
import) was crashing on FF 3 due to a stack size issue.  The prototypejs
code is using a matching regex to store the entire data part of the JSON
payload. No reason to do that - much more efficient to use string-based
functions to match the front and rear of the string.
