[New Feature]: Bulk regex renamer for items

[RubisDrake]

Introduction

Hey everyone, I've been playing around with the Bulk Rename feature in Kokua viewer, and it's super useful. I would really like to see this for Alchemy Viewer, and eventually Firestorm. Though I expect it will take their team a while to do it.

Description of the Feature

A Second Life viewer needs to have a Bulk Rename feature because LSL does not support item renaming currently. It can only rename things like objects and object descriptions, or folders that are given as inventory items.

• Description of its functions here: https://kokua.atlassian.net/wiki/spaces/KKA/pages/367984641/Bulk+Rename
• It allows selection from a checklist which inventory item types to affect.
• One text field has the single-line regex search term, the other is for the matched field.
• Allow an easy way to change filenames to all uppercase, all lowercase, capitalized words or maybe camel case.
• In Kokua, $& is a back-reference to the entire match, but it should also support $1, $2, $3, etc...
  • See here for more info: https://stackoverflow.com/questions/34510746/difference-between-1-and-in-regular-expressions
• Have a field that will let you choose if you want to rename (no transfer), or (no copy) items, or both.
• Have a field that can exclude items marked as "Favorite" or items in protected folders.
• Warn the user when there are (no modify) items that have been matched but cannot be renamed.
• Add any features that may be useful from Perl's Extended Regex library: https://perldoc.perl.org/perlre
• VERY IMPORTANT: There really should be a DRY RUN feature that allows you to show the results of a bulk rename without applying it. This makes is so that you do not have to drag a bunch of inventory items into an object to safely test bulk renames. Results of a bulk rename could be shown in a viewer floater/dialog window.

Maybe another future idea could be allowing bulk renaming of folders in an inventory, too. I know objects can't support folders, but that would be for the inventory only. And also something that can bulk edit the description field of each object. Though I don't know how useful people will find that.
