Removed hardcoded image input
Add stub classes for free transform and orient to path
Change touch transition implementation. Gestures are handled by their own interactors now.
Add free transform interactor, and removed translate interactor since free transform handles translates too.
Added OrientatePath Interactor

Not putting values for orientate to path and free transform into model
yet. Operator has to be changed to accept multiple transform inputs in
the same operation.
Merge branch 'master' of https://github.com/loosihong/ksketch2
Implemented interactors and reworked + cleaned up interaction state changes.
Fixed bugs with widget display. Plugged in time control into the mobile app.

Interaction
Widget's reactions to interaction events seem ok. Need to test more.

Transitions
Demonstration seems to be working fine. Interpolation is not working
(missing key to interpolate at the end of the process)
Redesigned widget and bug fixes for widget's interaction and appearance.
