Pluto 9.1.0

* Option to set the minimum box width for the expander. This is helpful if you have long captions on portrait-mode images or videos.
* Default dimensions for YouTube and Vimeo videos changed.
* Updated version of the Floatbox script. The previously encountered caption problems have been fixed.

* There have been several bugs in the Floatbox 8.2.x scripts that cause various problems with captions. I've reverted to Floatbox 8.1.3, which wasn't similarly afflicted.

* Option, when not using fixed-shape thumbnails, to constrain the aspect ratio (width divided by height) of the thumbnails, with a minimum of 0.5 and a maximum of 2.5. This prevents panoramic images and exceptionally tall, skinny images from producing thumbnails with extreme aspect ratios, which tend to distort the thumbnail table layout.
* Completely revised method for handling folders that don't have a representing thumbnail image. This includes the ability, when using the Custom style, to specify the background color behind the generic folder icon; preset styles use a color-matched background.
* Improved handling of thumbnail images that are smaller than the user settings require.
* Option not to hide the image counter on mobile devices (to save space, hiding the counter was the default in earlier versions).
* More selective copying and loading of resource files.
* More selective CSS inclusion.
* More efficient folder thumbnail sizing.
* Method for excluding unsupported objects altered to accommodate processing sequence in latest release of jAlbum.
* Album generation is aborted if you choose non-fixed-shape thumbnails, but also choose thumbnail image bounds that have an aspect ratio (width/height) that is less than 1.0. The justified gallery of thumbnails is fundamentally incompatible with portrait mode image bounds.
* Updated version of the Floatbox script.
* Default for video autoplay set to false.

* Option to choose alternate navigation icons for the "site home" and "album home" links.
* More selective generation of navigation icons to output directory.
* User-provided URL's are now automatically encoded, unless they contain the "%" character, in which case it is assumed that they have already been encoded.
* Updated import variable exclusion list.
