This means we don't have to new/delete them, which is a waste of
overhead.

This means we can also remove the forward declarations.
This is the first step in removing the memory allocation for the ui
sub-classes. Without the second step, this commit is just making the
compilation time increase for no good reason :-)

We don't really need includes of display.h and dive.h in
printoptions.h and printlayout.h or forward declartions
of 'struct dive' and 'struct options' in there.

By connecting to slots we always modify values at a previously
set 'struct options' pointer.
Also have the setup of slots and pre-set values in a
separate setup(struct options *) function.

The PrintOptions widget has value labels next to the
horizontal sliders. Add slots to update these labels
when a slider moves.
Patch also makes a modification so that the PrintOptions
constructor requires a 'struct options' pointer. If
an options struct is not received we do not set predefined
values and do not connect signals to slots, where
options will be updated immediately.

PrintOptions is a QWidget class to be used as an
addition to a future print dialog (possibly based on
QPrintDialog). Currently only contains a couple of
radio buttons.
PrintDialog (printdialog.cpp/h) which is a basic QDialog
is currently added for testing only and it holds
an instance of PrintOptions.
Calling File->Print opens this test dialog for now.
