STE tick optimization.

Browse source 
- SmartTileEntity#tick down to 3.32% from 11.64% cpu time.
 - Measured by JFR over 2 sessions each >8min.
 - Test world was the deployer fields.
 - Iterating over HashMap values is slow.
 - Collect TileEntityBehaviours into a list when the contents of SmartTileEntity#behaviours changes.
