The reason we want this is so that people do not forget to change the version number in the synapse module.
The precedent is that the version number has been 0.1.0 since the begging until now.
While this solution does mean that there may be new version of the module where
nothing has actually changed, this is still better than not changing the version at all.
Another version scheme for the module would be inconsistent to
the git repository tags and that has the potential to cause much more confusion
than "blank" version bumps.
If this is a problem, then antispam must be extracted to another repository.
In order to test this, run `yarn version --patch` observe the changes with `git log` and `git diff HEAD~`,
then YOU MUST delete the tag with `git tag --delete vd.d.d` when you are finished.
* more robust
There is no reason to call process.exit() from `index.ts` or in `Mjolnir.start()` because
https://nodejs.org/api/process.html#warning-using-uncaughtexception-correctly
>The 'uncaughtException' event is emitted when an uncaught JavaScript exception bubbles all the way back to the event loop. By default, Node.js handles such exceptions by printing the stack trace to stderr and exiting with code 1, overriding any previously set process.exitCode. Adding a handler for the 'uncaughtException' event overrides this default behaviour.
* Move message_limit into antispam.

Not ideal but we've had complaints about keeping them separate
and unfortunately the need for this module is not going to go away.
* standard protection consequences
* add integration test to make sure good users aren't banned
* the less far `event` propagates, the better
* better document consequence.ts
* improve innocent user integration test
* switch to room.event emit
* Test for batching ACL.
* Batch events from sync within BanList.
* Introduce the BanList.batch event to the BanList emitter to let Mjolnir sync after new events have been added from sync.
Fixes#203
It isn't clear what it means to have the server "struggle" with state requests.
This change is trying to make the configuration more actionable to end users.
