Editor tabs still holding on to database

[jungle-boogie]

Hi,

Similar to #18

Something in sqlite-gui is still holding on to the database after it's closed in the app. As a result, I can't delete or rename my database file. I haven't yet tracked down what's causing this.

I think the editor tabs are keeping the database in use.

1. Open sqlite-gui
2. Open database
3. Run query in new editor tab
4. Close editor tab
5. Close database but keep sqlite-gui open
6. Rename database file

Notice Windows says the file is in use.

I would expect sqlite-gui to always release the database once the application closes the file.

Thanks. I forgot to close a connection on a tab closing.

Fixed.
