This change makes it more inline with how QScrollArea operates on a central widget.
Other changes include using a QFrame instead of a QWidget as a base and
adding a QLabel for the title instead of the horizontal line.
The advanced options were split into their own separate widget. Right now
their class operates only as a container with the logic remaining in the
InstallDialog.
Do not hide irrelevant options, show them as disabled instea.
This like the install directory are still informational despite
not being editable.
Also homogenize variable and widget naming.
