sqlbrowser example: use idiomatic Qt [1/3]: disabling group-box

Browse Source 
The old code connected to the wrong signal and therefore had to write
a custom slot to perform the disabling of the group-box.

The new code simply connects the QCheckBox::toggled(bool) signal to
the directly-compatible QWidget::setDisabled(bool) slot, removing the
need for a custom slot.

Also move the connection into the .ui file, so it works already when
checking the form in QtDesigner.

Amends 2690822428deec4f0c08f4d118d69a7c6036369e, which, however, only
inherited the issues from older code.
