BPython:

- based on a request by Campbell (he also provided a patch for scene.Layer) access to layers was improved a little, keeping the old method (ob.Layers is a bitmask) and adding the nicer one (ob.layers is a list of ints).  Done for objects and scenes.  House-cleaning: .Layer was renamed to .Layers (actually just using strncmp instead of strcmp, so both work, same done for Window.ViewLayers).
- finally committing patch by Ken Hughes to let .clearScriptLinks() accept a parameter (list of strings) to clear only specified texts.
- doc updates and fixes (JMS reported a problem in nmesh.transform() example code).

Thanks all who contributed.
