[Enhancement/Feature] Add a 'paged' app drawer style

[joaocandre]

It would be cool if one could set a paged draw style as an alternative to vertical scrolling (something I've never found in any launcher since OpenLauncher went AWOL). Additionally, while I understand that the 'search' box is integral to the project, I don't really used it, would be nice if I could disable it in the settings.
