Jinja2 has a JSON serializer, but not a parser. This is the source of many StackOverflow questions and bug reports to projects using Jinja2. Add a function "from_json", which just calls "json.loads", to templates so that they can handle the JSON string in the "output" field of an event.

In our use cases, we sometimes have some JSON data that we want to format nicely for sending to another system via e-mail. We currently do that by having entire expert bots just to format the data into a string to go in the
outputfield of a message, which seems wasteful.With this patch, the Jinja2 template environment gains a function
from_json()(which just callsjson.loads()in the standard Python environment), meaning the Templated SMTP output bot can take strings containing JSON documents and do the formatting itself.
