    LWJGL 3.4.0 and Remove OpenVR

    @stephengold notified me that LWJGL 3.4 has been released and has also done some testing in their non jME projects with this new version already.  (big thanks for keeping a tab on this area)

    I still have most of my own jME projects running lwjgl2 ('ve been procrastinating upgrading to LWJGL3 for quite a while now, long overdue), so I will finally do so in my own projects so I can help test as well.

    OpenVR is also no longer supported in LWJGL 3.4.0 so it appears it needed removed, but (unless I'm mistaken) this should not be an issue since the Tamarin VR library is using the newer openXR, and openVR is considered outdated and deprecated. Any jME apps still relying on openVR can still use v3.9 or earlier without issue (@richardTingle correct me if I'm incorrect on any of this)
