Ability to smooth model animations

[HifiExperiments]

Closes #317

A new Model Entity property, animation.smoothFrames, to control whether we linearly interpolate between animation frames. It's true by default, but older content backups will default to false to maintain old behavior.

I have tested this on windows and can not see any difference in animation rendering, Everything appears to be in proper order and does what I would expect it to do.

@vegaslon to clarify, when you say "can not see any difference in animation rendering," you mean when the property is false? and then when it's true, you see it working as expected?

[vegaslon]

yes that is correct, Works great with setting false or true it is doing what I would expect it to do.
