microbit-dal: Revisions to MicroBitEddystone.

Browse Source 
This commit includes the addition of comments,
some validation and corrections to C++ definitions.

Also, a minor API revision for the Eddystone class, which
simple removes Eddystone from member functions, as it
it implicit that you will be setting a URL using Eddystone
in the MicroBitEddystone class.
