Rename "FX-Mixer" to "Mixer".

[claell]

Closes #3300 (hopefully, if not sorry for wasting your time!).

I currently only renamed String texts imho, but can also rename classes, variable names etc.

Not tested.

Ordinarily we'd target changes like this to master, but I see no reason not to target 1.2.

Also while you're at it, I'd personally be for changing variable names, though this is significantly more error-prone. Also I'm not as regular of a contributor as some others, so I'll let someone else weigh in on that.

Ah, alright, makes sense. Can I change this now to target to master?

Will also change variable names etc.

[josh-audio]

Before you target master, let's make sure nobody has objections to targeting 1.2. Changes to 1.2 are regularly merged into master.

You can't just change the target to master without breaking a lot. You would have to:

1. Clone master
2. Re-apply your changes
3. Create a new PR

Ok. Have created some more commits now to hopefully rename all instances of FX Mixer. I split it up into many commits to make it easier to follow the search and replace changes.

stable-1.2 is bug-fix only. Please re-target.

Not tested.

All changes should be tested. If not, you're asking the developers to test for you, which is asking them to work on a task you invented.

Why cause inconsistencies in the codebase?

Alright.

Well, I did not invent it, but ok. Is there a build artifact that I can use for easy testing?

Why cause inconsistencies in the codebase?

I don't know, I just heard that FX Mixer should be renamed to Mixer, so I thought why not go all the way. If this is not wanted, just say. Then I will try to only rename the relevant Strings.

Why cause inconsistencies Please do not cause inconsistencies in the codebase.

Closing to create another PR for master.

FYI, PRs can also be retargeted. It can get messy with largely-diverged branches like ours, so this is just for information purposes. :)
