resolve-local patch: - one a sym-link, the developer can decide, whether the resolve-context (for links, images, etc.) should be in the local package (i.e. the package containing the link, the form-field resolve_local is true) or the target package (resolve_local is false). However, .SELF. references refer always to the target package, which was incorrect in previous versions. This patch resets the the resolving policy under der .SELF. reference and allows for using both resolve_local choices.
