It's missing some highlights that we currently don't support, but it
comes very close.

Switchen from QMAKE_BUNDLE_DATA to QMAKE_EXTRA_TARGETS, like we
already do on Windows and Linux.
QMAKE_BUNDLE_DATA does not seem to create make targets. We need
to copy-if-changed the files into the resources folder on each run.

Also pushed the Resources/ folder one level deeper, into Contents/.

The crumble path shows the current context of the debugger/inspector.

Using more *::Constants::ICON_* where it makes sense and
wrapping the file names into QLatin1String where they were
missing.

The increased usage of the ICON constants needed a few more
cross plugin includes of *constants.h, here and there.
I think that it is OK, since the dependencies were alredy there
icon resource wise.

Uis in the core plugin should not use icons from the help plugin.
Also, let's use the Core::Constants::ICON_* instead of duplicated
file name strings.
