Plugin renamer (#393)

This plugin is an alternative to the native batch rename interface in
nnn. qmv from renameutils and vidir from moreutils allow to rename
files without fear of replacing existing files.

+# Description: Batch rename selection or current directory with qmv
+#
+# Notes:
+# - Try to mimic current batch rename functionality but with correct
+#   handling of edge cases by qmv or vidir.
+#	Qmv opens with hidden files if no selection is used. Selected
+#	directories are shown.
+#   Vidir don't show directories nor hidden files.
+#
+# Shell: POSIX compliant
+# Author: José Neder
