Stop animation from eating CPU when moving away

Use new ```stop()``` which was added in planetary,js v1.1.0 to stop eating resources such as CPU etc., see thread http://stackoverflow.com/questions/21365803/angular-with-canvas-animation-planetaryjs-jerks-after-switching-views and example in http://plnkr.co/edit/fqWRIE
replace by v1.1.1

includes UMD for global objects when using AMD loader, and new stop() method of v1.1.0
Merge https://github.com/darul75/ng-planetaryjs

Conflicts:

update to v1.1.1
format (Tabs), test scaffolding
remove scaffolding, add element.on(''...) to avoid hogging resources (CPU) and possibly memory leak when moving away from page without 'planet-stop'
re-add 'var stop;'
remove trailing line
add Async Dependency Definition (AMD) header with dependency on planetaryjs to enable async loading by RequireJS without shim, etc.
