Title: Bug 802587 - [Apps] Add placeholder icon to homescreen once installation is confirmed

+ goodies

This bug also includes the code for fixing:

Bug 802592: Replace placeholder icon with real one once installation complete
Bug 802594: Show downloading icon when app is downloading

Will need feedback from @etiennesegonzac, @benfrancis, @crdlc and @ferjm

It took me a while till got the proper animation with an 'aceptable' performance
