Title: Allow whitespace before name-separator in jsonKeywordMatch/Region.

The current keyword syntax highlighting regex successfully handles the
following json :

"keyword":"value",
"keyword": "value",

but does not match:

"keyword" : "value",
"keyword" :"value",

This patch permits keyword highlighting to work as intended in these
unsupported cases.
