[Update]: Camera projection first look

- It could happen that both parallel (orthographic) and perspective
projection will be in same *.html … only of course in separate tags …
[Fix]: Perspective
[Update]: Projection visual part at final state

- Still need to do interaction controls, besides moving global camera :)
+ Code clean up (it is a mess right now)
[Update]: Code cleanup

TODO:
- controls, a.s.o.
[Update]: Cosmetic changes
[Update]: Cosmetic and projection

- For now only ¾ orthogonal projection (still missing final projection
matrix)
- Made big cosmetic update (if not OK, we can go back to old look)

TODO:
- 3d google earth like navigation (for now only visual representation)
- itd…
[Update]: Option between persp and ortho

TODO:
- Projection matrix update (for now only visual representation for
ortho)
[Minor Fix]: Slider units
[Update]: Updatable camera projection matrix

- Camera projection matrix is not 100% interactive (it only serves for
visual representation)
[Update]: Added matrix-negation.html

- For now only random matrix generator on page refresh
[Update]: Added "colors-color_systems.html"

- Added missing sprites (now it looks more ok :)
[Visual Fix]: "colors-color_systems.html"
[Update]: Visual and architectural

- Camera projection now almost at it's final state
- Added visual guides for vector: angle, length, addition (at it's beta
stage)
- Fixed bugs in algebra...
- Matrix negation now with full screen window

TODO:
- mostly code clean-up ... for now
