- fixed multiple issues in the App objects related to wrong usage of self.obj_options attribute instead of self.app.options attribute

- remade the Film Plugin such that the `skew` feature is now done in length units as opposed with the previous usage of angles
- refactored some big methods from the Film Plugin
