Added Nunit and other stuff
Added relativeUrl column to DB sensor event and deprecated more stuff
Removed Dictionary from GpsHandler. Data is collected straight into JObject.
Merge branch 'master' into JP

Conflicts:
	MobileLoggerApp/MobileLoggerApp/src/mobilelogger/AbstractLogHandler.cs
	MobileLoggerApp/MobileLoggerApp/src/mobilelogger/Handlers/GpsHandler.cs
Handlers send log data using AbstractHandler into LogDatabase. Removed obsolete abstract methods and renamed sendSensorLog -> SaveSensorLog. Handler's relative urls are passed as a parameter to LogDatabase.
Removed legacy code etc.
