Add the possibility to remove table mappings

[kvegter]

In many cases you do not want to load the complete database. Especially with very big databases. So there must be a possibility to remove the tables from the table mapping. Normally you know your rdbms so maybe it is useful to apply a filter before retrieving the metadata from the rdbms, it will save time.

Hi, table filters are available in ETL release 1.2.0

At least in the command line, not yet in the UI.
