Added detection and thumbnail bypass for apng images
Adds apng sniffing when generating thumbnails with retained ratios to
serve the original image files, as we do for GIF images, to prevent
the image being resized to a static version.

Is more tricky than GIF since apng file mimes and extensions
are the same as png, we have to detect part of the file header
to sniff the type. Means we have to sniff at a later stage
than GIF since we have to load the image file data.

Made some changes to the image thubmnail caching while doing
this work to fit in with this handling.

Added test to cover.
For #3136.

Altered the parsing of custom head to prevent htmlentities on content
Was causing things like emjoi within script content to be somewhat
mangled. Instead we force UTF8 only parsing via XML declaration.

Added test to cover.

Fixed issue with HTML tags in custom head scripts
Fixes a strange issue of HTML tags within script tags being malformed
when part of the HTML custom head content due to the PHP parsing we do.
DOMDocument seemed to cause this upon load.
Adding LIBXML_SCHEMA_CREATE to the ->loadHTML call seems to fix this but
not really sure why. Doesn't seem to cause further issues though.
Tested with multiple scripts and styles and comments and meta tags.

- Also added new testing class to cover.
- As part of testing, added new folder within tests to house setting
  specific tests.
