* Add flake8 plugins
* Remove most ignores

This configuration will prevent CR from being committed. Qt Creator
is the main culprit here since there is no setting to change its
default line endings.
Include this config using the command:
 git config --local include.path ../.gitconfig

* Replace table widget with a table view
* Rename objects

Python code (project/ui/main_window.py) is generated from
qt/mainwindow.ui using pyside2-uic. Because it is generated, flake8 is
configured to ignore the project/ui directory.

* Add a playlist model for the tree view

An SQLite driver is being used. The database consists of a single table
which has fields for metadata as well as the file's path and CRC32.

ffprobe is used to retrieve metadata in JSON format.

json.loads seems to be able to decode an encoded string just fine, but
this is some added convenience in case `stderr` is to be read.
