Fix JSON nodes, improve binding generator, add external types to AssemblyInfo.cs and mark enums as data model types

[Nytra]

Marks necessary types as data model types

Improves binding generator to use constraint clauses and generic types attribute

Fixes JSON nodes, create value and object variants of the nodes

Closes #42

[Frozenreflex]

I'm already redoing the Json nodes

[Nytra]

@Frozenreflex How are you redoing them?

[Frozenreflex]

@Nytra Check my branch

[Nytra]

@Frozenreflex I think adding the generic types attribute to the binding generator would be a good idea because then you can populate the common generic types list in the UI

[Nytra]

@Frozenreflex Also, you can't connect ProtoFlux value inputs to ObjectInput<T> it needs to be a ValueInput<T> that's why in my PR I split the nodes into Object and Value variants.

[Frozenreflex]

why do i put up with this game's bad design choices

i'd already encountered that for the outputs, but i guess i didn't test the inputs, gonna do that in a sec

[Frozenreflex]

public struct ObjectInput<T> : IObjectInput<T>, IInput<T>, IInput

public class ObjectOutput<T> : Output<T>, IObjectOutput<T>, IOutput<T>, IOutput

public struct ValueInput<T> : IValueInput<T>, IInput<T>, IInput where T : unmanaged

public class ValueOutput<T> : Output<T>, IValueOutput<T>, IOutput<T>, IOutput where T : unmanaged

why

also i fixed it if you want to look at it

[Nytra]

@Frozenreflex

Should be ValueInput<T>

@Xlinka I think Frozen's branch should be merged then I will make additional PRs later
