subprojects: Prepare for release

As get_frontmost_application() and icons rely on being able to inject
our internal agent into SpringBoard.

Down the road we might be able to reimplement this functionality as a
helper program that we spawn inside the Simulator runtime. The uncertain
part is whether we'll be able to give that program the appropriate
entitlements.
