Web-based formspec edtior

Really actually removing the pains of formspec design.

Try it online

Uses Fengari to run my formspec_ast and fs51 mods on web browsers.

image[] elements use HDX textures by default (dynamically loaded when required).

Major features

• Web-based (no waiting for MT to load)
• Dragging and resizing elements.
• Property editor
• ${lua code} substitution in text values.
  • Don't remove the weird comments generated when exporting these formspecs if you plan to import them again.
• The ability to load existing formspecs (provided they are version 2 or above).
• The ability to export to (but not import from) digistuff touchscreen formspecs.

Limitations

• Although it can save formspecs in the version 1 format, it cannot load them in this format. Co-ordinates are backported with help from my fs51 mod.
• The properties editor is slow when manipulating lots of properties.
• Malicious formspecs imported with the ${...} substitution option enabled can freeze the webpage.
• Element alignment might not be perfect.
• I haven't tested this thoroughly in many browsers, if you find any bugs please report them.
• Texture modifiers in image[] will not be displayed in the preview.
