Set maxitems to 50000 for Event log cleanup in archetype

Current setup from archetype:

keepitemfor: how long items should be kept after they were created specified in milliseconds.
-1

maxitems: maximum number of items allowed in the event log.
-1

This means currently no logs will be cleaned up. In most cases you'd like to clean up more to reduce overhead. For instance, this can result in a lot of data and long indexing during startup. Suggested is cleaning any items over 50000 by setting maxitems. By default this will be done at 3 AM in the morning every night.

More info:
Indexing 50k log nodes should take around two minutes so it
isn't a big deal. Having the millions of log nodes is a big deal.

The logs are used for:

• recent activity plugin on the dashboard
• regular listener on the event bus. This is used when you create code to receive these events, otherwise it is not used.

Naturally you can / should adjust according to your own needs in your project.
