September Week 4 Director Commentary video!

• Further improved performance for avatars without fingers.
• Added the internal-side stuff to permit you to re-define grab attach points on a per-avatar basis. This will allow hands to grab objects differently if the avatar has unusual hands, and will allow character creators to define where objects rest in the hands of the character. I need to make the tools for this still but now it's there to have tools made for it.
• Pointers no longer collide with your real hands. This was never intended to happen and was interfering with the virtual scale system when you define yourself as a very small character.
• Defined a point in space to calculate the position of a character's mouth. We'll make a tool for defining this in the N-Entrance tool. For now though I just need a vector3 out of it.
• Added the ability to define a grabbable object as grabbable only by a specific controller. This is useful for situations where you have independent grab movement for a left and right hand (giant weiner for example) or a specifically handed object that you wish to deny the ability to pick up with one hand.
• Added a unique grab behavior for a character's mouth. Objects that can be mouth-grabbed automatically mouth-grab when they intersect with this point. At present this grabs objects that can not physically move and serves as a secondary type directional grab, but if people want to role play as a character without hands to grab with by choice we can add additional functionality to give you a mouth-grab button or something. I'll need feedback on that.
• Modified the hand interactors to be angled slightly differently. Object orientation wasn't matching the rotation properly between hands.
• Added some additional meta data to the hand location. It's impossible to do a normal vector direction calculation (vector3target-vector3source) when the points are identical. Now there's an always available "up" vector from the hands that I can use to code against.
