Allow a folder name to be specified below which all resized images will be stored within their resolution sub-folder.

The resolution cookie format convention inherited from the original Adaptive Images implementation separates the screen width value from the pixel ratio with a comma, e.g.

480,2

But it seems that Tomcat will not read cookies set by javascript which contain commas, which results in a fallback to testing the user agent string and delivering either the min or max configured sizes according to whether "mobile" is found.

To avoid this, we need to support cookies which use a hyphen instead to separate the two values, e.g.

480-2

The javascript to set the cookie will need changing to the following to use a hyphen instead of a comma:

<script>
document.cookie='resolution='+Math.max(screen.width,screen.height)+'-'+("devicePixelRatio" in window? devicePixelRatio: 1)+'; path=/';
</script>

If there are no cached files left after clean up, delete the cache folder as well.

Currently logging is quite verbose. The option to just log errors would be useful to diagnose production errors in a more minimal fashion.

The file operations cache speeds things up by avoiding repeatedly checking file/directory existence. But if the cached image files or folders are deleted without updating the cache, this will result in 503 errors.

Reset the cache if a file/directory existence error occurs.

Sometimes important to know which image caused the error.

e.g. "/images/test.png?1234" will cause: "invalid extension 'png?1234'".

Lucee has a BIF FileInfo() which is significantly faster than GetFileInfo(). Use it if the engine is detected as Lucee.
