Adding white + navy blue dress

[ThePotatoGuy]

#4550

Key changes

• White and Navy Blue dress with bunny scrunchie from @Velius94
• bunny-scrunchie ACS type with template. muxable with ribbons
• the bunny-scrunchie also only works with non-twintail ribbon hairs
• _acs_wear_if_gifted - only wears an ACS if it has been gifted/reacted to
• Exprops now will have constants in mas_sprites. we'll do this on a rolling basis. I need to update the wiki first.
• the hair tie selector now filters hair ties based on the current hair. This means no single-sided ACS (the bunny scrunchie, black bow) when wearing a twin-tail hair style
• ponytail-braid hair style no longer has the twintails prop

New exprop

• excluded-hair-props - value should be a list of hair props that are in compatible with this ACS

TODO

• thumbs
• select dlg if desired
• dlg-desc
• determine what the blue ribbon thing is. We can't really use Ribbon (Blue) because it looks different than the normal ribbons.

Testing

• verify that the clothes + acs look good
• in outfit mode, the clothes will swap to a ribbon + non-twintails hair style to wear the bunny scrunchie.
• verify the bunny scrunchie and black bow cannot be worn with a twintail hair style
• verify the hair tie selector does not list bunny scrunchie or blackbow if a twintail hair style is worn
