This starts to address several items in the roadmap, but probably doesn't fully address any of them. It takes the plugin code that was written several months ago, before the scope of this project was fully sorted out, and refactors it to be a starting point for the roadmap.
* Adds template files for form inputs that can be used to both create new pledges and manage existing pledges
* Does some validation and sanitization work on form submissions
* Adds a custom post status for deactivated pledges
This avoids the complex mutliply-nested blocks and makes the block style less reliant on a custom class. On mid-sized screens, we switch to plain horizontally-overlapping rectangles, and on small screens we stack the columns, and vertically-overlap.
Also, remove the parallelogram styles from the editor display. The skew and positioning don't work well in the editor context.
Looking at ITCSS, it appears the last level should be `utilities`. Since that's a name that has no negative connotations, let's use that instead. Also add a README documenting each folder's use.
Removes es6-promise, which is not necessary for local development (we're all on a modern version of node).
Moves the sass file generation to a separate function, the current IIFE method is not clear.
Update autoprefixer's browserlist to use the core WordPress configuration
Add a default task, and map grunt in npm scripts
