/** Links Qt widgets with server manager properties by name.

A Qt widget will be considered a "match" for a property if its name is
any one of the forms:

PropertyName
PropertyName:String
PropertyName:Digit
PropertyName:String:Digit

... where PropertyName is the name of the server manager property in question.

The first form is the most used, when there is a single Qt widget associated
with a property.

The second form is used when more than one Qt widget will be associated
with a single property.  An example would be a property controlled by
a slider widget plus a spin box.  In this case the two widgets might be named
"Foo:Slider" and "Foo:Spin".  The choice of identifier for individual widgets
is not significant, as long as it is unique.

The third and fourth forms are used when Qt widgets will be associated with
multi-element properties.  The digits are used as indices to control with
which property element a given widget will be associated.

If widgets can also represent domains (combo boxes has a fixed list of items,
sliders or spin boxes have a minimum or maximum value), their domains will be
linked as well so if the domain changes, the possible values or
minimums/maximums will automatically updated.
