When designing pads, it can be helpful to not only see the resulting
rounded rectangle radius from a given percentage but also to set it,
constraining the related percentage. This adjusts the dialog to allow
editing the rounded rectangle corner radius. It does not change the
file format as the resulting ratio is saved. Further updates of the pad
size or ratio will modify the radius.

Also fixes a bug where nets wouldn't get changed because the
pads weren't changed and so the pad nets would propagate and
wipe out the changed nets on the tracks.
Also includes warning dialogs that pad nets will be changed if the
track nets are.

Well, almost anyway. We can't use a pad attribute for them as
that would change the file format. So they're currently
defined as a CONN pad with no copper layers.
However, when figuring out of existing pads should be *treated*
as aperture pads, we just check for no copper layers.

This patch enables math expression evaluation for most of the text input
controls in pcbnew.
NEW: pcbnew text input controls are able to evaluate simple
mathematical expressions, including distance units (e.g. 5.0+(2*1.2mm)).
Add a hack so that the pad properties base dialog constructor can pass in the dependency. Since the derived dialog's constructor takes the parent by this exact type, the static cast is safe.
