Support covers

[klinker24]

I hate to steal from Action Launcher, but this is an amazing feature, in my opinion.

Covers are similar to folders, but instead of a single click opening the folder, a swipe will open the folder, and a single click will open the first item in that folder.

This is good for grouping similar apps and cleaning up the UI.

Not exact clone some things are less than covers but it can help in starting to implement this feature.
