OpenVR SDK 0.9.15

General:
* Several event members have been changes from enum values to plain-old-data types to guarantee compatibility across compiler vendors.

IVRSystem:
* PollNextEvent() and PollNextEventWithPose() now take a parameter for the size in bytes of the VREvent object you are passing in
* The data member in VREvent_t is now variable length and at the end of the structure. 

IVRApplications:
* Added VRApplicationProperty_LastLaunchTime_Uint64, which returns the last launch time for an application in seconds since January 1, 1970.

IVRCompositor:
* Compositor_FrameTiming is totally different. What should we tell people, Aaron?

IVROverlay:
* Added the ability to render an overlay wrapped around a component on a tracked controller when in the dashboard or compositor.
* k_EGamepadTextInputModeSubmit added for chat-style use of the keyboard where instead of a "Done" button there is a "Submit" button and it doesn't make the keyboard go away.
* PollNextOverlayEvent() now takes a parameter for the size in bytes of the VREvent object you are passing in
* For overlay applications there are now two new event types you can listen to, VREvent_Scroll and VREvent_TouchPadMove. These events are generated if the VROverlayFlags_SendVRScrollEvents or VROverlayFlags_SendVRTouchpadEvents flag is set on your overlay window.

IVRRenderModels:
* Added RenderModelHasComponent, which returns true if the named model has the named component.
