(Animation) Added component index to allow animation of separate components of a Vector

[Issue#]   N/A
[Problem]  Other than internally fixed components (e.g. POSITION_X), sub components of a Vector property could not be animated, creating a need for some properties to be split into multiple float values
[Cause]
[Solution] Added componentIndex parameter to Property() constructor
