Add note about move semantics in Output comment.
Use implicit move semantics for Timeline.

We don't need to spell out the move ctor (on OSX, at least).
More flexible TimeType definition.
Move TimelineOptions declarations to separate file.

Makes Timeline file easier to read.
Update sample/test projects on OSX.
Raw pointer methods safe to call from callbacks.

Still not recommended.
Include glm vectors directly in test.

Instead of going through Cinder; buys us some generality.
Restore explicit move ctor for VS2013
Test file adjustments Win.
Sample project change on MSW.
Move ctor tweak.
