Pytest-tui

- Fixed Issue 94 (KeyError when user env has no JAVA_HOME).

- Fixed Issue 84 (dataclass exception with Python 3.11).

- Implemented internal tracking of Rerun tests.
- Added Rerun test sections to the HTML page.
- Added duration to existing start and stop times for test session.
- Changed look 'n' feel of About page in the HTML report (uses accordian buttons now).
- Moved initalization of pytest-tui-specific Config object attributes from pytest-sessionstart to pytest_cmdline_main, as that method seems to be visited by the code earlier. This is to prevent AttributeError seen while testing latest build: "AttributeError: 'Config' object has no attribute '_tui_test_results'."
- Internal implementation of pickling now uses a single file for TestReport and Section data. The pickled data is in the form of a dict, and also has some timedate info in it.
- Tweaked and formatted a bunch of the tests in /demo-tests.

- Added '*' .gitignore to tui_files/ so that when people run pytest --tui in other directories they don't see the tui_files/ dir.

- Addressed issue 63:
- Fixed tuih and tui console scripts not running
- Removed autolaunch feature (TUI and HTML pages must now be launched by the user using 'tui' or 'tuih')
- Removed config script 'tuiconf'
- Pinned dependencies.
- Added pytest-metadata to dependencies.
- Removed bullet from dependencies.

- Added "All Tests" results tab.
- Removed "nth child" css code which was masking result button highlighting on hover.
- Added start_time and outcome to each test result button in HTML.
