Clean up extraneous table row nesting.
Switch to a linear layout for this simple design.
Add start / stop button to layout.
Wire up the start / stop Proximity Kit button.

Use one button for ease of UI changes. While not the best idea, keeping
a state flag is simple for a sample app.
Fix the URL in the properties file.

The website is now a sub-domain off of the main radiusnetworks.com
domain. Newly created properties files reflect this. This updates the
existing file with this new URL.
Fix incorrect minor version for Proximity Kit lib.

In order to use beacons the minimum SDK needs to be 18, not 9.
Fix incorrect manifest file.

This is not required for Proximity Kit. The `launchMode` setting is
specific to how this sample app works. In order to properly handle the
main activity UI's list, only a single instance should be created at a
time.

This was missing from the initial release.
Improve debug messages to include the state.
Fix :bug: where the UI list was not cleared.

Clear the internal row map when the activity manager is stopped. This
fixes a bug where after starting the `ProximityKitManager` a second time
the UI list is not updated. This happened because the inner row map was
not cleared, so the beacon was thought to already have been seen, thus
it was not re-added to the view; however the view itself was already
cleared.
Use the 0.2.0 version.
