Added test tool to return what java thinks is the host and user name of
the machine its run on
BUG FIX: If database is missing key server config settings program
wasn't null checking before attempting to parseInt/Long.  Added null

instead of crashing with a null/NumberFormatException
Added Strings for Call Log Panel
Prelim work for Call Log Panel (based on caller history)
