* Allow custom filters for the JSON data to be pushed into the DOM for individual widgets
* Limit information about ancestors when pruning pages
* Better error messages when data illegal in JSON is passed to pushGlobalData
* `jsonAttribute` filter escapes ' rather than " if { quotes: 'single' } is passed as option argument, resulting in a major readability and bandwidth savings. You must single-quote the attribute when using this, so it is not the default
* `apos.escapeHtml` also supports this option
* Reduced excessive whitespace in the DOM using nunjucks {%- and -%} (still a lot of it)
