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.
PHP syntax checking was being weird so I spent some time to make some
corrections. The problem was I was just using the wrong protocal, PEAR
when I've been coding to the PSR12 standard. Easy fix.
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.
