Viewport - Black and White template/style (not only black)

Right now default template/style is generaly Black .

• This mind that any image saved from vieport have black background and white/orange wireframes, etc. everything is determined by this style
• This doing problem for prints, etc. re-use of image without render in case image can be used just from viewport omiting whole process to adopt final work/image in case early images from viewport are enough.

I know is white template for whole GUI, but I think user should have this option to easy with betwen black and white viewport, not GUI.. Reason is due of used black object sometimes, etc.

By this feaure request expecting option fast switching in:

• View > Viewport style - Black
• View > Viewport style - White
• View > Viewport style - Blue (prints)
• View > Viewport style - Green

Feature is related with: Shading - Random colours as not random (Spectrum/Gradient for childs)

• to optimize works with viewport
• made this sometimes draw/sketch like CAD style

• the mockup replacing colour black/gray to white only (it's not perfect job - but we see the sense ; )
• missing sketchup easy change style
• maybe this can be done in simple way
