[FEATURE] customizable attribute forms using Qt Designer dialog UIs

- add support for checkbox edit type and edit forms for vector layers
- selection of ui file in vector layer properties (general tab)
- the forms are opened when a feature is added or via identify.
  The widgets on the ui have to be named like the attribute they are supposed
  to edit or show.  If the vector layer is not in editing mode, the widgets
  will be disabled
