Preset for iZugar Z2XL180 now available

This is the preset for the VR180 configuration by iZugar. The support is not perfect: Mistika will still generate VR360, so you need to crop the renders in the next stage of your workflow (aka in Premiere, typicaly). Usage: Apply the preset, use "Improve Offsets". Also, you may use "Improve Angles", however this not always work correctly, specially if the zone is strongly asymmetrical. Consider this an experimental preset, we will be glad to hear about how successful you were using it. If somebody does use other VR180 configurations, let us know too.
