Fix stars not respawning + other syncing fixes (#460)

* Force secret stars to respawn

Hacky fix for sure. I'll need to see how to deal with this in a better way.

* Improve star syncing

All stars now respawn (hopefully) and the red coin star no longer repeatedly respawns.
Also forced oSyncDeath for other objects.

* Remove leftover include

* (Probably) improve star syncing

It'll still spam packets but at least it'll only spam packets to people who are able to receive them

* Revert "(Probably) improve star syncing"

This reverts commit 86ff2c5451cff0a06e8c3410b2815e12b414f264.

* Weird sync

No idea why this works but it does. At least no fields have to be synced over, as far as I can tell.
