This PR addresses a few tickets, addresses issues found during app dev, and groups the changes together because the changes were generally not huge for each fix.

• Adds a DefaultCurve entry, SigmoidUpDown.
• Fixes a bug where having any ISpaceComponent in a child of an Interaction Behaviour affected the space of that Interaction Behaviour even if it was not associated with any physical collider of that Interaction Behaviour. Interaction Behaviours still support a maximum of one (1) custom space. However, custom spaces used to warp LeapGraphic attachments on the Interaction Object will no longer break interaction with it.
• Adds window-resizing to our default project settings. This is intended to fix an issue with the VR Visualizer not being resizeable, but that relies on a custom build process, so may require future attention.
• Deletes the RigidbodyWarper script and the dangling properties for Interaction Behaviours, since they weren't being used.
• Adds an IgnoreCollidersForInteraction component and updates the InteractionBehaviour to ignore colliders found that are directly given this component. This is intended to address an issue where trigger colliders used e.g. for raycasting when building custom interactions-at-a-distance would also affect e.g. the grasping interactions for that object.
