Fool-proof plug-in load

Fixes #61

Special Case Fix

This also addresses a special case of querying connections to elements of an array.

b["arrayAttr"] = Long(array=True)
b["arrayAttr"][0] >> a["ihi"]
assert a["ihi"].connection() == b
assert a["ihi"].connection(plug=True) == b["arrayAttr"][0]

This didn't use to work, as the plug was automatically converted from a networked to non-networked plug using findPlug. And it didn't like indices in the name given, e.g. worldMatrix[0].

strict=True

Turns out, MSelectionList.add() is lazy. It'll accept the shortest path to a node, such as myNode even though the actual name is someNamespace:|myNode. So, does myNode exist? No! That's what strict does.

assert cmdx.exist("myNode", strict=False)
assert not cmdx.exist("myNode", strict=True)
assert not cmdx.exist("myNode")  # New default

The inputs method was from the Node class which could have multiple inputs.

Oh yes.

These latest tweaks should have gone into its own PR, but sometimes one can be lazy.

• Return native Quaternion types for asQuaternion() and inverse()
• Make Divider attributes non-keyable per default
• Append to existing animation cuves if they exist
• Add minTime(), maxTime(), animationStartTime(), animationEndTime()
• Add Vector.isEquivalent
• Add Quaternion.asEulerRotation
• Add Quaternion.inverse
• Add TransformationMatrix.setRotatePivot
• Print rotation of TransformationMatrix in degrees rather than radians
