Add a dev mode that allows for local storing of config files and logs (#1682)

Allows vorta to be called with the command-line flag `--development` or `-D` that will make it use a directory in the project tree to store all the settings, logs, and cache. This default directory will be called `.dev_config` and placed in the projects root.
Also allows for a custom directory path allowing for multiple "configuration" folders at once.
This can be used to prevent the vorta instance that a developer is working on from accessing the configuration files that they have set up for their personal backups.

* .gitignore : Add `.dev_config`.

* src/vorta/utils.py (parse_args): Add `--development` flag. The default will be `DEFAULT_DIR_FLAG`.

* src/vorta/utils.py : Add `DEFAULT_DIR_FLAG`.

* src/vorta/config.py : Add methods for populating the config directories exposed by this module.

* src/vorta/__main__.py (main): Handle `--development` flag and update config directories if its specified.

* Access config constants through the `config` module instead of importing them directly with `from .config import`.
