BuckleSystem: stop setting every interaction as handled

[whatston3]

About the PR

Sets handled to handled when an event is handled.

Why / Balance

When clicking to interact with, say, a mothroach, to pick it up - for whatever reason, the BuckleSystem has priority, and sets all interactions as handled.

Jesus Christ.

How to test

1. Checkout master.
2. Spawn mothroach.
3. Click mothroach. Nothing happens. HMMMM.
4. Checkout this branch.
5. Spawn mothroach.
6. Click mothroach. Pick it up. All is well.

Media

Safely in hand.
