Add support for Jumpgate campaigns

[kakaroto]

Looks like Jumpgate uses a different format for drawings, the data.paths of a page now has these changes:

• Instead of a json.serialized path, it uses points and shape instead
• Instead of left and top, it uses the x and y fields
• The width and height seem to be unused

Also, pages don't how "showlighting" anymore, so the lighting system likely changed and needs to be investigated to find what other changes there are with Jumpgate games.
