New layout in DataTableWindow with JXTable

[GoogleCodeExporter]

Set up of a JXTable instead of JTable and a new layout easier to execute query. 
It is possible to make a SELECT with the right-top corner button of the JTable, 
a SORT BY directly with the columns, a WHERE with the Textfield area and a 
LIMIT with an other TextField area.
