`image-dired-dired-insert-marked-thumbs' to
`image-dired-dired-toggle-marked-thumbs'.

* image-dired.el: Require cl when compiling.
(image-dired-dired-toggle-marked-thumbs): Rename from
`image-dired-dired-insert-marked-thumbs'.  Add ARG.  Doc fix.
Use interactive spec "P".  Set LOCALP arg of `dired-get-filename'
to 'no-dir.  Skip files whose names don't match
`image-file-name-regexp'.  When file has a thumbnail overlay,
delete it.  (Bug#5270)
