Relic Save/Load Fixes

Turns out Relics were broken in a few different ways with the save/load system.

When quitting and resuming a run, relics would disappear from inventory but their effects would persist which must have been super frustrating.

Also, the  Beach Ball Relic which gives you +1 ball was broken even more than that and was not loading correctly when you had that in your inventory.

Also also, fixed a small bug where you couldn't sell a relic when the Drop Zone help text was on screen.

All that should be fixed up, give it a good test and see. Sorry for the frustration.

On to more bugs that all you very helpful players are finding for me!
