* Updated grab/equip logic to use sphere vs sphere tests, instead of sphere vs entity bounding box.
* Added debug flag for visualizing grab spheres.
* hotspot overlays are now updated as the objects they are attached to move.
* You can now use the search beam to near grab large objects, as well as the sphere sphere test.
* Optimized EntityPropertyCache to make a single call to Entities.getEntityProperties instead of three.
* Moved grab script options from the "Developer > Hands" menu to the "Developer > Grab Script" menu.
* before this change the releaseEquip message was not getting sent to the bow,
which it would use to re-enable the grab script via the 'Hifi-Hand-Disabler' msg.
* Removed entry into HOLD state via secondary aka grip buttons.
* Changed equip logic to prioritize equip over near over far grabs.
* Added drop gesture, upside down controller + slight shake + trigger press
* Bug fix for near grab snapping to an incorrect offset after a far grab (this bug is present in master)
* Moved the update logic from STATE_NEAR_GRABBING, STATE_HOLD & STATE_EQUIP into the entryMethods
for those states.
* Removed STATE_CONTINUE_NEAR_GRABBING, STATE_CONTINUE_HOLD & STATE_CONTINUE_EQUIP states
This functionality has been moved into the updateMethod for their respective states.
This *should* be a pure re-factor no functionality was changed.
* When trigger is depressed, any entities that are marked with a wearable equip-point
will become highlighted by a wireframe box (temporary art).
* The grab state machine is now defined by the CONTROLLER_STATE_MACHINE object.
this includes each state's name and updateMethod name.
* Support was added for entry and exit methods when changing states, this
functionality is used to draw and delete the hot spots when entering
and exiting the searching state.
Don't intersect with grab balls (not just lasers as before).
Don't run grab lasers through (2d or 3d) overlays.
Don't try to manage reticle in handControllerGrab because other scripts
do.
