Moved the back button to the left

Moved the back button to the left by using a boxLayout with glue. The
other components need to be inside their own panel otherwise the JTextBox
will explode.
Moved the database label

Moved the database label to the left so that it is easier to read. The
panel it is in now has a boxLayout as it's manager. The other label and
the combo box are now in their own panel so that the combo box doesn't
explode. Things like to explode for some reason.
