Classify class and struct constructor separately

[laicasaane]

So they can be styled differently.

@laicasaane, it looks nice that classify destructor separately from methods (or just not classify it), but I don't understand why do you want to classify .ctors class and structs differently?! And seems that this feature is redundant if issue #24 will be added to extension, because you will can recognize .ctors types, doesn't it?

[laicasaane]

It's really just some fancy taste of me. I like the .ctors to have the same color as their type, be class or struct.

@laicasaane, I moved the issue's part about a destructor to the separate issue #26
