V-REP-VR-Interface v2.0

Release notes:

• Changed to VTK 8.2
• Objects can now be dynamically loaded after the interface booted (option to disable this is in HTC_VIVE object)
• Headset pose is now also available in V-REP
• Basic interactions can be imported as models (dummies) that can be attached to controllers
• All signals that VTK provides are now available in V-REP (20 integer signals + 12 float signals)
• A shift of textures is visible in the interface (think of conveyor belts etc)
• Added menu model. This allows the definition of menu text and corresponding functions, that when these texts are selected in VR, trigger the execution of the functions in V-REP.
• The interface respects visibility layers. Visibility layers can be changed after the interface booted.
