[Beta4] Sphax VectorialShape

There is too many modifications since last beta version and I've not wrote the list of all the new features.

But here is a non exhaustive one:
- general: New icon
- general: The object is now compatible with MMF2 movements (but some features are not currently fully compatible)
- general: The object can now check if it's in collision with another object
- general: Support for SVG format (import/export)
- action: "Refine the shape" to automatically add points where needed
- action: "Set position of a new point" to add a point at the end of the shape (it was possible before with "set position of a point" but it's now faster with this new function)
- action: "Set number of points to display" to make the shape partially drawn on the frame
- action: "Collision mask to BMP" to export the collision mask picture
- expression: "Get area" in 3 versions, both are more or less precise (all are approximation).
- expression: "Get most far pointID from coordinates" to get the point ID which the most far from coordinates
- expression: "Get nearest pointID from angle" to get the point ID which is the nearest one from coordinates and angle
- and more...

Bugs corrected:
- Some glitches appear when the rotation of the linear gradient is at 360° (don't know if I can do anything against that)
- The object does not follow correctly the frame if the layer has a coefficient different from 1

Known bugs:
- The object is not compatible with HWA mode but all non graphical features work well.
- The object can be 1 frame late when scrolling

Enjoy.

This version IS the version PhysicDraw uses (but without Messages Box).

It will possible in future, allow you to create multiple shapes with the same object with ID for each shapes?
> Not in this object, maybe with the future new one (VectorialWorld object or something similar) but you can currently create several instances of the same object with different points (like PhysicDraw do)

It would be practical to create custom hotspots in frame
> Invisible points with visible points... Maybe I'll add it but currently you can do it with two objects.

VectorialWorld should be an object exactly like VectorialShape is but which support unlimited shapes retrievable with name...
But this object is not planned currently and will not before VectorialShape is done. Keep in mind that you can already done a lot lot lot of things with VectorialShape object.

Look at your ".\examples\sphax vectorialShape object" folder DJFuego.
