Generate JSON output on each deployment.

[yukiisbored]

coala has been changing and maturing every day, it would be preferred to generate the JSON output on each deployment rather than making them stale.

#143 needs to be improved and merged first though.

@yukiisbored shouldn't this issue belong to coala repository. or is this issue related with this repository ?
Also would like to work on this, can you explain how can we achieve this ? Do we have to run coala --json on coala core repository and save it somewhere ?
