#309: static Equals not used

Fixes #309

[SimonCropp]

happy to accept this as a change but not in its current form. walking up the hierarchy for every type is not ideal https://github.com/Fody/PropertyChanged/pull/310/files#diff-0475c87a808e41b1f849062b31c9a3d3R85

this type of information should be stored in TypeNode https://github.com/Fody/PropertyChanged/blob/master/PropertyChanged.Fody/TypeNode.cs on a single pass then used on all classes when injecting

[jhartmann123]

I couldn't really use TypeNode, as those are only created for the types defined in the assembly that gets currently weaved. As I obviously also need the equality comparers for properties with types defined in other assemblies, that's a small show stopper.

Instead I'm filling the (already existing) method cache a bit more aggressivly, so the type hierarchy only has to be run down once.

Example:

class A : B{}
class B : C{}
class C {
   static bool Equals(...)
}

When looking for the static equals on A, after the method was found on C, the cache gets filled with a reference to the method for all three types A, B and C.

I hope that's a bit better :)

Sorry, sometimes I'm an idiot and can't see the easiest solutions...

Equality info gets stored in the PropertyData now - I can move it up to TypeNode if you want to. Either way - it gets loaded in one pass while filling the TypeNodes now.

thanks. this is now deployed. although nuget might take a few hours to update its index
