Fix T42961: GPencil - Refactor object/scene data behaviour

Browse Source 
D937 with minor edits (whitespace only)

@aligorith, I double checked everything runs smoothly, blame me if I missed something ;). Sorry for just taking the initiative and committing without talking to you, but I wasn't able to catch you the last days. This should be fixed before the release IMHO, but I don't think it's important enough to be committed during BCon5, so sorry again, but hopefully everything is okay :)
