VAM Plugin: Toggle Targets as in Desktop mode

This plugin will make the toggling of targets (the green squares to control objects in the scene, light symbols, camera symbols etc.) behave in VR in the same way as it behaves in desktop mode.

In vanilla VaM, the targets are shown when you point your VR controller in their direction and will disappear when you point your VR controller away from them.

With this plugin, the targets can be toggled on or off with the T key on the keyboard, regardless of where you point your VR controllers
