Comet Rename Plus+

A Python adaptation of the original MEL script:
"Comet Rename"
by Michael B. Comet
http://www.comet-cartoons.com/melscript.php

A nice renaming utility that allows basic Prefix, Suffix, Search & Replace, and Rename+Number methods. Works properly on any hierarchy, even if renaming nodes in the hierarchy out of order.

This new Python adaptation includes several quality-of-life improvements:
* Same window instance keeps the user's text input the same every time you open the tool.
* Clear text built-in button to easily clear each line.
* Capped padding at double-digit value to prevent accidental crashes when renaming with a name that is too long.
