* Don't finish the fragment from the controller (ugh!) instead just report the selected icon via a listener.
* Highlight the selected icon in the list.
* Cache the icon drawables (since we're using selectors for the colors, we don't need to swap them, one per icon resource id is enough).
* Improved the tests a bit too.

* Propose icons from com.android.internal.R instead of android.R (as a proof of concept) since this is what we'll be doing with the final icons.
* Provide the icon options as a parameter to the controller (can also be used for testing).
* Fix some Lint warnings.
