"Batch Object Name Edit" allows you to change multiple names of Blender
objects at once.  It provides options to define if you want to: replace text
in the current names, truncate their beginnings or endings or prepend / append
strings to them.

Usage:
Select the objects to be renamed and run this script from the Object->Scripts
menu of the 3d View.
