Added initial connector API

Adds a DefaultConnector and a KitsuConnector. These connectors can be
used to retrieve task_types and shots from an external system.

The default connector is used as the default configuration when a
configuration key isn't defined.

Loading production configuration

The configuration of the production is now loaded from the production itself.

Added vscode to gitignore

Moved WindowManager struct to global instance.

Added Addon Preferences + New Shot File operator.

The shot file operator uses the add-on preferences and current file to
detect what the root of the production is. It is prefilled in the
operator.

Operator does not do anything yet.

Added option for center of world to the example configuration.

Added an example configuration

Initial example configuration was extracted from the design. It will be
updated so the API can be discussed with TDs.
