Changed Audacity*.{cpp,h} to Tenacity*.{cpp,h} in src/

[DemonicSavage]

I removed many references to Audacity from the src/ folder. I get that this is very intrusive, but it had to be done sooner or later.

References to Audacity are a blocker for 0.1.0, so I renamed some files.

Thanks for doing all this

Don't worry about the macOS build fail, that's a common issue with CMake, not something you changed

[DemonicSavage]

Sure. Let me know if there are anything that could be added to this PR!

Everything alright with the DCO bot? It seems to be waiting.

I think it's time. Let's go for it. I'll let this PR rest for ~5 days or so, just in case anybody else disagrees.

Just a reminder, no one disagrees.
