Major update!!!!
Created two BroadcastReceivers-classes and exported a BReceiver class
from the BlueController. The application is now listening for changes to
the state of the bluetooth adapter and its connection-state. This it to
properly update flags that can help rebuild the lost connection.
A bit of restructuring the folders and renaming classes.
More work was done in BlueController. It now has a cleanUp()-method that
can be invoked by BackgroundOperationThread when it is turning of.
Created a collection-package.
