Update 16JUL24

- Fixed an error causing menu buttons to edit the inventory with incorrect values.  This issue was causing the inventory to crash the game. Set button variables to clear whenever the menu was closed to prevent attempting to populate as empty.

- Fixed an issue where the game would drastically lag over time and faster with more rooms unlocked. When a new room tier is purchased, it adds corresponding treat recipes to the queue list.  However, this was happening EVERY frame for each room unlocked, causing major performance issues and eventually crashing the game when the queue became too long. Altered the queue to only add new items once when a room is spawned.

- Added a label to the upgrade shop button. In the top left, the coin pile opens the upgrade shop and allows purchasing the required rooms. This was not clearly explained. The option is now simply labeled "STORE" until a better method is used.

- Edited unused upgrade and unlock buttons. Various items in the upgrade shop have not yet been developed and are included just as placeholders. Previously, clicking them would take you to a different level of the menu, now clicking should do nothing.

Thank you to Neocortex for pointing out these issues.
