Plugins Video Renderer for 3D VR180, VR360 and Flat 2D & Audio + BVH Animation Recorder

- fixed video recording not actually stopping automatically for non-integer recording times (now integer only)
- added preview resizing and preview crosshair
- preview window is now always square when rendering VR
- added support for LilyRender360 smooth stitching (improves results when rendering some forms of post-processing, but increases VRAM consumption)
- increased default preview FOV to 140 to better estimate VR view
- default MSAA to off, filename empty
- remove infobox due to lack of space

- Fixed incorrect field of view calculation for preview and flat renders
- Fixed preview window in wrong color space
- Preview window now remains open during render to verify correct orientation

- Added 2:1 aspect ratio and more options for 1:1 resolutions

- Game's physics rate now remains untouched. Instead using Unity capture time setting for frame rate control.
- Changed hotkeys

This should only affect the case of rendering faster than the physics rate, such as when using the frame skip option.

Version 1.1

- Added flat video recording, with supersampling by MacGruber.
- Mute all sound while recording.
- Added preview window.
- Added hotkeys.
- Fixed 6K, 7K, 12K resolutions
- Reduced VRAM consumption slightly.
- Improved memory estimate (maybe).
- Added warnings for texture size and VRAM consumption exceeding capabilities of GPU.
