Adventure Overhaul +custom border +paritions (#47)

ADVENTURE OVERHAUL
* Adventures can now customize both halves of the card, allowing for two pages.
* Each side can be an Adventure page, an Adventure page with only a name, a full text page, a flattened Adventure page, a flattened page with only the name, or blank.
* A decorations field has been set up, which allows adding additional flair around the pages to help set variants apart.
* Also we have better page images now.

PARTITIONS
* Partitions are finally live!
* Frames can add the card field "partition select" to access partition code, no additional scripting is needed.
* MSE handles partitions 0-9 and A-Z. Assign cards partitions 0-9 to sort before the default count at A, B-M to sort after it, and N-Z to sort after it and not be counted in the main set count, for card numbers like 301/300.
* The Set field "last main partition" allows the user to change the behavior by putting a replacement for M in the option.
* Card numbers default to the March of the Machine numbering of "0001" now
* But 001/099, 001, 1/99, 1, and 1000/0099 are now supported, with a second option to set overcounted cards to display with or without the main set count.
* Currently this is supported on M15 Mainframe and M15 Adventures. The rest are coming soon.

EXTRA THING
* Added Custom Border support to M15 Mainframe and M15 Adventures, which let you use magic-mainframe-extras to set up an additional border frame akin to Nyx and Vehicle. This is the finalized version used for Revolution's Ruin and Colorless frames.

BACKEND STUFF
* Adventures is trying out some new backend stuff that will get expanded upon in the coming patches:
* retooled the Landless array to be less jank
* retooled the template script a little to make it easier to hook out images with complicated links, most notably user-submitted ones like custom crowns and custom borders
* blend masks are now in their own folder
* discovered that 'styling.name or else ""' is legal code in script, which means we can make adding style options to frames *way* easier. the entire custom font code is now offloaded to scripts, and templates can access it without needing to copy paste anything beyond the styling field.
