Add tag replacement to Image Tag Decorations

[ThePotatoGuy]

Key Changes

• Adds using a different image tag for a decoration depending on background
• deco definitions per background now include a replacement tag in addition to the frame
• to use replacement tag functionality, pass in a replace_tag param to the register_bg/register_img/register_img_same functions
• The deco ADF test topic has been updated with an example of tag replacement in operation
• mas_isDecoTagVisible now means that the decoration (or replacment tag) is actually showing, not just when its enabled.
• fixed issue where showing/hiding deco without the show_now or hide_now params didn't show/hide the deco at all.

Testing

• test the TEST DECO ADF dev topic

You deprecated mas_isDecoTagVisible, but it's still being used in a few places. I'd probably even replace it with mas_isDecoTagShowing in mas_d25_monika_christmas.

Should we handle this now or later?

Looking at the other spots its used, it seems like Visible should just mean Showing, so instead just changing the meaning of the function instead of deprecating.
