Show editor window listed by project, then project-relative path
|Reported by:||adamk||Owned by:||azawawi|
As good as just sorting by the file name is, we can go one better.
The text for each file should be the project-relative path to the file, for example
The ordering of the windows should be two-layered, first by the filesystem path of the project the file is contained in, then by the project-related path to the file, with files always sorted above directories at the same level, so that Makefile.PL always appears before lib, and lib/Foo.pm always appears before lib/Foo/Bar.pm.
