TestDbConnection

TestDbConnection is now split up in several dedicated programs:

• TestDbConnectionCode: database connection data like server, login etc can be written in the code or interactively given to the running program.
• TestDbConnectionSettings: use settings file to read the database connection data from (or enter them the first run).
  Todo:
• version to circumvent the "NoSSL" problem with certain mariadb client software

There is a file included to make the example database: db.sql
