Simplemouse fixes (#669)

* fix: Simplemouse bounding box size fix
* fix: Bug when exiting game with simplemouse with disconnecting non-connected gamepad
* fix: issue-339. Simplemouse gives an error in the debug when you move on/off ESCItems
* fix: tracks mouse position to allow for mouse tracking as well as on-demand tooltip updates on immediate target change, i.e. rendering doesn't lag a frame behind.
* chore: decouple further by using a signal
* fix: Correct action getting randomly lost with simplemouse
* fix: deleted objects aren't always equated to null.
* fix: clear the tooltip when an action is finished.
* fix: clears tooltip only on successful event completion; debug code cleanup.
* Broken room 5
* fix: Item collisions correctly determined when game resolution = screen resolution
* Update addons/escoria-core/game/core-scripts/esc_item.gd
