Plugin lists are universal across clients and OS-specific cases
should be appropriately handled.
OSes can now be added to the deeplink action case and Ferrite scans
for either iOS-specific or fallthrough actions.
There must be 1 action that corresponds to an OS and/or 1 fallback
case, otherwise the action will not show in the plugins list.
Also remove some extraneous files.
