Can't jump to package imported by custom identifiers and can't jump to method / property of struct definition

[bom-d-van]

Can't jump with custom identifiers:

import bar "awesome.com/pkg/foo"

bar.VariableOne // Can't jump from here 

Or methods or properties of structs:

type Foo struct {
    Name string
}

func bar() {
    var foo Foo
    println(foo.Name) // Can't jump from here
}

I think these two are quite common problems, yet I can't find explanations of why they are not working.
Any helps or explanations would be appreciated.

Margo (the backend) currently doesn't support jumping to a field of a struct (there's a TODO in the code).

I believe this is fixed with my changes in #571
