Eliminate IOType.fromCoreType

[samreid]

From #263, I would like to eliminate IOType.fromCoreType. It was introduced as a convenience method, but it is making the type checking very complex and difficult, and making it difficult to make progress in classifying the different state serialization types.

We also now have well-established patterns and examples and type checking, so using the IOType constructor can be used safely. And it will be nice to have one way of doing things instead of two.

To make sure I didn't miss any use cases, I instrumented fromCoreType to output the different parts that are being passed through to the options. Here are the results:

Some notes from this issue:

TODO: Because serialization involves accessing
TODO: Why do some of these things just have stateSchema????

if it has either toStateObject or stateSchema, then it must have both

if it has toStateObject, it must have fromStateObject | applyState | {
stateToArgsForConstructor
applyState
}

Reopening.

Changes like this one in natural-selection violate PhET naming conventions.

- Bunny.BunnyIO = IOType.fromCoreType( 'BunnyIO', Bunny );
+ applyState: ( t, s ) => t.applyState( s ),

Abbreviated names are discouraged, especially names like t and s that convey no information.

I have a hunch that this is what it should be, but I'd have to dig around to be sure:

applyState: ( bunny, stateObject ) => bunny.applyState( stateObject ),

@samreid you did applyState: ( t, s ) 6 times in natural-selection, 1 time in projectile-motion. Please use more descriptive names.

[pixelzoom]

@samreid I see similar naming violations for toStateObject and fromStateObject in the above commits. Please fix those too.

[samreid]

Good idea, I improved the parameter names in the commits. Please let me know if I missed any.

Did you mean to assign this to me for review? I took a peek, looks like you got them all. Feel free to close.
