[Bf-python] Layer handling inconsistant

[Willian Padovani Germano]

Hi,

Today I added an object.layers attribute (the current one is called 
object.Layer and uses bitflags) that works just like Window.ViewLayer(), 
accepting and returning lists of ints.  I'll commit it tomorrow with Ken 
Hughes work on .clearScriptLinks() (he made it accept a list of text names).

I had also made Window.ViewLayer use G.scene->lay instead of G.vd->lay, 
conforming to recommended practices, but then the screen is not updated, 
so the function also needs to update G.vd->lay, when G.vd is not NULL.

 From my early tests it's working fine, but a friend came in and I had 
no time to commit today, sorry.

Campbell: not a bad idea having a scene.layers, too, will do it.
