Tiny BASIC in Python 1.0.0!

• Added the %exit command language command to exit the tbp debugger. Closes #1.
• Now tbp behaves like a normal command line application when the user hits CTRL+C and CTRL+D. Closes #3.
• Fixed the copyright on top of all Python files. For some reason I thought it was 2004. Closes #43.
• Added the combined coverage report summary to the CI.yml output. That makes it easier to see what didn't have coverage. Closes #44.
• Added the tiny_basic_grammar.ebnf and grammar_tests.txt that I forgot to bring over from the dead repository. Closes #45.
• Added better error reporting on INPUT entry errors and escaped syntax error strings, so characters like \n are displayed correctly. Closes #46.
• Did a pass to eliminate any dead code. Closes #47.
• Did a final editing pass on all documentation.

Detailed Changes: 0.9.1...1.0.0

More documentation and fixing GH Actions vs. Branch Protections

• Fixed CI.yml to work around the bug in GitHub Actions where matrix jobs don't have any status of the sub jobs. See #41.
• Added the GitHub and GitHub Actions section to the documentation.
• Added the pyreadline3 dependency to the documentation.
• Updated the README and Getting Started Installation section to point to the Latest releases.
• This is basically a practice release to ensure I have the steps down. 🤞 (Thanks for your patience!)
