Feature/is app cache ready

[mikklfr]

Added isAppCacheReady to know if there is a native app cache.

Sample code : sugarizerOS.isAppCacheReady(function(response) { console.log("IsAppReady : " + response.ready); })

ready is a boolean

To try the functionality, you can call the sampleCode

• inside the homeview, before initActivitiesPreferences
• inside the homeview, in the init function

The first call should return response.ready => false The second call should return response.ready => true
