card_fields rewrite and magic-modules.mse-include (#21)

Overhauls the card_fields file to allow for template designers more freedom in manipulating data.

Adds magic-modules.mse-include, a large scale include file for building templates in a standardized way. Applying this to existing frames will be coming in future updates.

+#### This include contains standardized assets and code that can help with template creation.
+#### To add a module, see the detailed instructions in it's folder's readme.
+
+#### Globally, you must respect the following z index conventions:
+-100:	hidden			#### Backend things that should never be visible to the user
+0000:	backboard		#### Things (other than the main card frame) that layer behind the art
+0100:	illustration	#### Main card art
+0200:	background		#### Main card frame. Will need a mask to allow clicking the art beneath.
+0300:	trim			#### Effects like vehicle, nyx, and snow that don't spill over the border
+0400:	pinline			#### Colored pinlines, pride pinlines
+0500:	border			#### Border
+0600:	plate editing	#### Major frame pieces: Transform sym/Lesson/Spree handling, Adventure pages, movable typelines
+0700:	watermarking	#### Watermarks, loyalty ability stripes, flavor bar, pop-under art (ex: WAR JP Tamiyo's popout goes under the rarity symbol)
+0800:	attachments		#### Optional frame additions: Crown, ptbox, level arrows, loyalty boxes, stamps, color indicators, alias box, flash dot
+0900:	text			#### Any text, rarity symbol
+1000:	overlays		#### Popout art, foiling and other overlay packages
+1100:	corners			#### These must always be last
+
+
+Notes on z index conventions:
+
+z index can't be scripted, so choices made need to be consistent across a wide range of templates
+As such, the card frame goes over the card art:
+This means normal card frames need to use a frame mask
+Because the alternative is frames like devoid must layer the art over the frame, which is untenable
+
+Trim effects can spill over the pinline and frame plates (such as snow's textbox effect).
+However, these will be overruled by conflicting effects at the higher z index (such as Adventure pages).
+
+The main functional difference between "plate editing" and "attachments" is how they interact with watermarking.
+When that isn't relevant, consider if the effect is editing the standard version of the frame layout, or adding an extra thing on top
+Crowns are treated as the later in the code to allow for more custom crown freedom, even though they do more resemble the former
+
+Text can go at lower z indexes if it's meant to be obscured or behind the watermarking
+But generally any user input text should be in the 900 level, on top of all the frame elements
+
+Overlays primarily refer to .mse-include packages that add foiling and other effects, as well as the popout art.
+Templates sometimes refer to things like the Vehicle trim as overlays, but these don't belong in this z index unless they must layer over text.
+
+Corners are functionally a special kind of overlay to standardize corners, and get their own section to ensure they always apply last.
+This has the minor drawback that popout art can't be applied to the most extreme corners for square-corner cards.
+The invisible corner option has been added as a workaround for this.
