Demo Owning Type Arguments

[ambiguousname]

Adds FunctionOwningType:ParameterType as a default way of labeling parameters.

Fixes #713, intended to fix #611 as well.

I realise this wasn't clear the way I filed the issue, but I was thinking of using the parameter names, not the types. The reason is that there can be two parameters of the same type, but they would have different names.

We'd maybe even want to do both

This is why I'd love for this information to be passed down to the renderer in a structured fashion: My ideal UI for this is something like this with <fieldset>

[ambiguousname]

I think that'd be fantastic! Fixes for using parameter names are in.

I'll open an issue for adding more context in RenderInfo (and updating the default renderer to use <fieldset>)

[ambiguousname]

Just one note, if the parameter is the self parameter, the default labeling will show up as something like Self:ParamName. Is that desirable? It might be less ambiguous to replace self with the owning type of the function.

[robertbastian]

I think self if fine for now.
