Warmachine Card Creator V4

... And now there's a V4!

Changes from V3:

• It is now possible to overlay and independently position multiple background images when loading images from URLs.
• There is now and option to flip the small data box alignment. It will be automatically set to run left-to-right if there are more than 6 stat blocks.
• It is now possible to have up to 7 model or weapon stat blocks if the life bar is hidden.
• Numbers have been removed from health boxes, although they can still be added back manually.
• The mini spell box now resizes automatically.
• Added file upload options for background images, profile images, and icons since local paths don't work unless running the web page locally.
• Replaced "import/export" options with single card/all cards JSON options (more future-proof as it only saves data, so more likely to be able to import the data in the future).
• Unit health rows can now be hidden.
• The unit health area is now raised if the fluff box is hidden.
• The fluff box and unit health area are now raised if profile image is hidden.
• Can now have up to 8 model health bars in unit health box.
• Increased size of model name boxes in unit health area.
• Added a more efficient font to save space in some fields.
• Added an importer for importing data directly from the app.
• Rescaled card elements and added an option to set the page size to try to make printing easier.
• Added an option to scale up the warbeast damage spiral.
• Added a separate colour control for damage boxes.
• Automatically shrink ability text to fit available area.
• Replaced base size icon with a text field next to the name.
• Increased number of health boxes in life bar to 30.
• Fixed some display issues.
• Added the ability to print hardpoint option cards.
