Array properties create a new view of the array on validation

[fwkoch]

When validating an Array, a new view is always created - see here:

properties/properties/math.py

Line 129 in 9fd6fb0

value = self.wrapper(value)

This results in some strange behavior, especially with using Arrays as DynamicProperties:

I propose adding a coerce key-word argument similar to container properties:

properties/properties/base/containers.py

Lines 170 to 172 in 9fd6fb0

	* **coerce** - If False, input must be a tuple. If True, container
	types are coerced to a tuple and other non-container values become a
	length-1 tuple. Default value is False.

Then if coerce=False we would skip the new view creation step.
