Patch for New Customer dialog

[micwise at bellsouth.net]

I have been thinking about ways to get involved with development.  I have looked at the dialogs and beleive I might be able to help.  I have attached a patch to make the New Customer dialog more in line with the GNOME HIG.  I'm very new with glade so I hope I've got some things correct.  Let me know if you have any comments or if you find it usefull.
