Special thanks to Zeus.

Also some Pit/Palutena fixes and adjustments for the meta files of many characters.

To support forthcoming line functionality that can assess whether an item of clothing sounds plural, each character will need to be updated with a `plural=true` on selected lines in their wardrobe list.

With mod permission, I am going through and updating the xml files of characters who have had no content edits in the past six months. If you were working on an update to any of these characters, feel free to overwrite these changes. However, remember to flag the relevant clothing items as plural in your text document or Character Editor.

As Chell, Chica, Daisy, Daria, and Dawn were all made with make_xml, I have rebuilt these behaviour files using their original text documents. This unearthed additional targeted lines from Chica that I believe were always intended to be part of her behaviour file.

make_xml loves shuffling around the order of tags, but I have not changed the order of any tags in this series of commits.

Move ALL opponents (except the re-skins) into opponents/. Include all opponents in listing.xml, giving unofficial opponents status attributes.

Official and testing opponents are included in deployment by way of a python script. Only official opponents will be included on the individual select screen, unless additional status classes are listed in config.xml (e.g. <include-status>offline</include-status><include-status>testing</include-status>).

This simplifies status changes since directories don't have to be moved around and we don't have to specify full paths in listing.xml. It also simplifies code since we don't have to extract the opponent id from the folder path.

Unlocked epilogues will also work with offline/incomplete opponents, and stay unlocked if/when those are moved to official status.

As she has the fewest unique lines for a non-silent female character (194), Dawn has been moved off the main roster and into the offline_opponents folder. Should a contributor wish to mount an attempt to revive Dawn, they are welcome to make improvements and then submit her for the testing tables where she will be subject to the same sponsorship standards as any character wishing to enter the main roster.

Fred's xml changed significantly because make_xml orders the situations
differently than they are in his file. I looked through the history of
changes to his behaviour.xml both on GitLab and on GitHub and included
the few manual adjustments I saw since his first inclusion.

This wasn't causing problems for normal browser play, but it would cause
the game to load improperly in other environments.

This update includes characters from A through D

All released characters should now have a <release> tag indicating the
relative order in which they were officially released in the game.
WIP characters in the repo do not have this tag, but it should be added
when they are officially completed.
Release numbers were automatically added by an external script, which also
seems to have converted some tabs to spaces and moved some comments, but
there should be no change to the meta.xml data (other than the new <release>
tag) otherwise.
