AddGoComments can not use "windows" paths with backslash

[kmpm]

This is not a big issue but I noticed that on windows when constructing paths using path.join or related the comments
did not load. But if I replaced all the backslashes (normal microsoft) with slashes (the rest of the world) it works.

Slashes works
reflector.AddGoComments("github.com/lavoqualis/messages.go", "./sources" )
but backslash
reflector.AddGoComments("github.com/lavoqualis/messages.go", ".\\sources" )
doesn't.
