Add Fill From Database Manager Option

[xantari]

The database manager has some useful information such as Author and sometimes better table descriptions and data we could put into the comments field.

Implement the auto fill feature similar to the Ipdb Fill Function in the Add/Edit Game screen.

Perhaps hinge on the source url to be filled in to get the data as that could be the key to lookup the table information. For instance if a table came from vpinball.com and the vpinball.com/downloads/... was filled in, we could look it up in the database from that url key to fill in missing fields.

Provide a popup window to select which field data to keep, and to save those preferences.
