Composer dependencies were pretty old, so they needed to be upgraded to
the latest.
There was also a minor bug that was triggered when a new page was saved
with empty tags and no images or documents, so that's been patched as
well.
Added markdown table conversion to the html process so we get sexy
tables. Also updated the version number to prep for the latest beta
realease. Ha, took a minute but we're back on track
I needed some consistent php formatting, so I plugged in a php fixer
config and then reformatted all PHP files so it's all consistent.
Fixed an ID issue with the page-edit template that was causing page
editing to fail.
