[HuggableShark]

Issue summary

Description of issue:

Steps to reproduce:

Terminals full of minerals with little to no energy

Suggested fix (optional):

Have either the Manager or Queens remove extraneous minerals and drop them to place energy so that transfers can occur. They can recover dropped minerals as necessary as the terminal empties.
