Passive Item Update

June 12th, 2019:

Over the last several days I have been adding the capability to have passive upgrades as you progress through a run.

This necessitated the creation of items, a new screen, and a global stat system in order to apply dynamic stat changes to classes of objects.

Now that this is implemented it should be relatively straightforward to add many items and stat changes.

Next I will be working on the ability to receive new towers in addition to these passive upgrades.
