Regular expression is slow in get_json

[dstelzer]

There's a noticeable delay in each call to get_json. Since the cruft at the beginning is always the same, why not use a slice operation instead of a regex?

To make get_json work for as long as possible. Maybe one day Facebook decides to remove the for (;;);. And then everybody who's not using the latest version of fbchat, will get screwed over ;)

Would it be faster to do something like

i = text.index("{")
if i > -1: return text[i:]
else: return ""

I'd imagine it would have the same behaviour if so.

Try testing it's speed, and if it is indeed faster, then make a pull request

I did the speed test, and included your code in a commit somewhere ;)
