Adding damage cooldown/"invincibility frames" as in Live (#1276)

Browse Source 
* Added cooldown handling

* Made most of the logs hidden outside of debug mode

* removed weird submodule

* kill this phantom submodule

* updated to reflect reviewed feedback

* Added IsCooldownImmune() method to DestroyableComponent

* friggin typo

* Implemented non-pending changes and added cooldown immunity functions to DestroyableComponentTests

* add trailing linebreak

* another typo :(

* flipped cooldown test order (not leaving immune)

* Clean up comment and add DestroyableComponent test
