Update sisyphus to v1.1.103
Include sisyphus 1.1.107 for development
Exclude Gravity's hidden fields
Use only form ID, name is excessive and caused extra writes to local storage
Gravity uses descriptive IDs on everything and using the name attribute caused problems with mutli-part fields.
Rather than use a generic submit event (which breaks sisyphus functionality on multi-page forms) bind, instead, to Gravity's actual submit button
Remove old minified file, implement build system
