Figure out how to Destroy Improvements

[ChaelCodes]

Describe the Feature

Is your feature request related to a problem? Please describe. When Improvements are destroyed, the Hunters Improvement still exists. These could be destroyed, but that wouldn't remove the benefits these improvements incurred.

Describe the Technical Implementation of the Solution

Solution When destroying a HuntersImprovement, remove the benefit it conferred to the Hunter. Create a remove_improvement method on HuntersImprovement, and add a remove_improvement to each type of improvement. When the HuntersImprovement is DESTROYED remove the improvement and refund 5 experience.

Let's remove the ability to destroy improvements, only allow them to be deprecated. Deprecated Improvements cannot be added to a new hunter.
