Favoriting packs and collections should now be supported by the system.
Below are some details for the implementation.

Favoriting and un-favorit a pack/collection:
This happens in the packs details page, there is a favorite icon in the header:



Once favorited, the icon remains orange and the tooltip displays "Remove from favorite"

The user can click this icon again to un-favorit the pack/collection.
It works like for sound items.

Displaying favorites:
The favorited packs and collections should be display in the "Favorites" tab inn packs view.
There we display:

• Favorited Factory packs 
• Favorited Factory collections
• Favorited user's collections (personal and shared)

Note: the factory collections are using rectangular images, we will find out later on how to fix this issue in the favorite tab
