The auto theme feature (case-sensitive) checks for the name of the system in RPG Maker (not case-sensitive), not the name of the file

[Mimigris]

This currently causes an issue with the menu theme EBroxas_menu_1 in Uneven Dream since while this is the name of the System file both in the files of the game and for the menu of the site, it is referenced in RPG Maker as Ebroxas_menu_1, making it not be loaded while using the auto ui.
