DbInfoCode for Gambas3

When I noticed I couldn't run DBinfocode for Gambas2 anymore, it was time to convert it to Gambas3.

The first part is somewhat finished:

• Connect to a database (login password are saved for easy re-connection)
• see the existing databases and tables (depending on your rights of course)
• Use kind of template with standarised id and update metadata fields to create a new initialised table.
• Not only create an initialisation for the table, but also give extra fields at creation.

Todo: from the table, generate the code for an object with get/set and persistance.... (see v2)
