Merge pull request #8 from cleercode/master

Bunch of code cleanup
Merged scripts

- Merged the output of images and states
- Fixed a bunch of stuff to be Objective-C
- Added * for flattening
- Fixed transitions

Bug: Slices still crash sketch. Very annoying bug that I’m hoping is a
problem with Sketch beta.
Moved to Framer 3

- Moved framer.states to use Framer3
- Added git hub curl to get Framer rather than linking to public url in
index.html
- Added @@hidden back in and @@mask, but not sure that’s the best way
to handle it, or if it works.
