KNewFileMenu: fix creating symlinks with a relative target.
Review Request #128451 - Created July 14, 2016 and submitted
KNameAndUrlInputDialog::url() makes URLs absolute (which is useful in general, for e.g. passing to KIO), so I added urlText() to retrieve the text as is. This removes all the code about showing an error on remote URLs; we just create symlinks to the requested target, whether it looks like "../foo" or "a:/b" which could be a relative path too (although an unusual one). Bug misreported as a comment in bug 352927.
Created a symlink to "../anotherdir" in konqueror/dolphinpart using "Create New" / "Basic link to file or directory...", the target now stays relative.
I looked up who wrote that symlink creation code in order to add him as a reviewer .... turns out the author of commit 8684162 in kde-baseapps is .... me.
