Version 0.1.4 - Just some polishing

On this update:

• Several annoying bug on the viewport configuration
• Added model height positioning slider
• Added grid for measurement
• Better filtering for viewport, improving the output image

Planned improvements for next version:

• Rewrite UI using tabs for better control organization. UI seems cluttered.
• Create options for output image filtering
• Add Option for Applying shaders on top of the 3D view
