Enable liquid.strict_variables in _config.yml

[TWiStErRob]

Not possible yet, because:

• _includes use include.param syntax and there are many optional params, e.g. toc.panel, or alert.classes

  twisterrob.github.io/_includes/toc.md

  Line 10 in ebc93f6

  {% if include.panel or site.kramdown.toc_panel %}{% assign show_panel = true %}{% else %}{% assign show_panel = false %}{% endif %}

  twisterrob.github.io/_includes/alert

  Line 30 in ebc93f6

  <div class="alert-box {{ entry[0] }} radius {{ include.classes }}">{{ entry[1] | markdownify }}</div>

  twisterrob.github.io/_includes/snippets/email.html

  Line 8 in ebc93f6

  * safe(optional) = true|false, if not provided it will only be generated if site.safe mode is on

• there are some site.data.filename[hashkey] lookups, e.g.

  twisterrob.github.io/_includes/tag_cloud.html

  Line 12 in ebc93f6

  {% assign tag_data = site.data.tags[tag] %}

• complex array items are not defined, e.g. video.url vs video.youtube in

  twisterrob.github.io/_includes/video.html

  Line 1 in ebc93f6

  {% if include.video.url %}

  twisterrob.github.io/_projects/chroma.md

  Lines 16 to 17 in ebc93f6

  	videos:
  	- youtube: 'ADC9suV2v4U'

• ad-hoc hash lookups like page.images.inline.titles

  twisterrob.github.io/_projects/screenjunkies.md

  Lines 9 to 14 in ebc93f6

• default layout params are not inherited, e.g. noindex in

  twisterrob.github.io/_layouts/xml-style.xsl
