Simplify preference filename configuration

[trevordevore]

New syntax:

preferences: user: default: [optional default name] macos: [macos name] ios: [ios name] windows: [windows name] android: [android name] shared: [same as user]

@spencerlearning This PR changes the syntax for preferences to match the data folder syntax. I think we discussed making this change. Can you review and confirm?

[spencerlearning]

@trevordevore It looks good. The app.yml preferences section needs to be changed for this to work. Also, preferences filename instead of just preferences makes it more clear:

preferences filename:
  user:
    default:
    macos:
    windows:
    linux:
    ios:
    android:
  shared:
    default:
    macos:
    windows:
    linux:

@spencerlearning I've updated the app.yml file. Anything else?

@trevordevore What do you think about making it preferences filename: instead of just preferences:. "Preferences" is pretty vague for the new user (is it referring to a folder, a file name, default values?). Adding filename makes it clear.

Also, a trivial thing, but you might consider moving linux below windows so the platform ordering is consistent with the application data folder section:

preferences filename:
  user:
    default:
    macos:
    windows:
    linux:
    ios:
    android:

If you make it preferences filename you will need to change the line in prefFilenameForPlatform from

put "preferences" into tA[1]

to

put "preferences filename" into tA[1]

@spencerlearning I agree with the "filename" addition. Done. I also reordered "linux". Any other thoughts before I merge?

Everything looks good.

@macMikey FYI preferences syntax has changed in app.yml

[macMikey]

And just like that it goes from "what do you think" to boom. done, before I can even say "yeah, I like 'preferences filename'"

Got to get to a 1.0 release :-)
