Additional service details with major refactoring

• New service details lookup from search results.

• Upgrade to Gradle 5.6

Improved Audio Support

Initial Train Departures Android App

Includes:

• Soap client for talking to the Live Departure Boards Web Service (LDBWS / OpenLDBWS) https://lite.realtime.nationalrail.co.uk/openldbws/
• Basic Android app that performs live departures lookups between two given stations, currently uses raw CRS codes but have plans to support searching using station names.

Requires:

• A developer API key provided by OpenLDBWS to be able to work, this is only a prototype for now not a full fledged app for the app store.

• Single search results with saving of each response [default]
• Multiple search results refreshing the entire board on each search

There is also a hidden feature to speak out the first result (regardless of search type chosen)
