Improve trusted-replace-outbound-text scriptlet

Browse source 
When the replacement starts with `json:`, it will be first
decoded using JSON.parse(). Example:

example.com##+js(trusted-replace-outbound-text, somefn, json:"ok")

The doublequotes are required since this is what JSON.parse()
expects as a valid JSON string.
