PFA patch for 5583 support schema level restrictions and edit connection properties when already connected.
Details as follows: 1. Schema restrictions :
1. Added a new tab "Advanced" in the database properties, with the "Schema restrictions" option it is similar to the "DB restrictions" in server properties.
2. Added new table "databases" in the SQLite database, to store schema restrictions per database.
2. Edit connection properties when already connected:
1. Now allowing a user to edit server connection properties when the server is already connected, here the user will get a warning for disconnect and reconnect the server to apply the changes in configuration.
