Check Tracker Performance

[sonoftunk]

Currently, the display for the check tracker is being updated as fast as possible. In reality, the update cycle only needs to happen on one of a few events

• File Load/Unload
• File Save
• Scene Transition
• Interaction (button presses)

The groundwork for performance was started with f638ae0. It's currently still checking every single save location on every single draw frame.

A performance mode option was added with 865d3cf. Issue not entirely resolved.
