Pluto 7.0.0

* Revised navigation options and icons. If a URL and text are entered under "Album > Settings > Pages > Link to homepage," a "site home" icon is shown on each page of the album. If "Link to album home" is selected under "Pluto > Layout > All Pages & Index Page > All Pages," an "album home" icon is shown on each page of the album below the top level, which takes the visitor to the top level of album. As before, an "up" icon is shown on each page of the album below the top level, which takes the visitor to the level immediately above the current level.
* Some minor CSS tweaks to improve positioning of navigation icons.
* Improved positioning of titles and navigation icons on small displays, including a fix for one bug that would sometimes make a navigation icon inaccessible.
* A fix for a bug with the "top of page" action in Safari.

* Option to display a "top of page" navigation icon when the visitor scrolls down through the thumbnails. The size and opacity may be chosen, and when using the Custom style, the color of the icon and its background may be chosen. If you open a project created with a prior version, and were using the Custom style, the skin will use its "best guess" for colors for the icon and background, but you should check them before making an album.
* Some small color adjustments.
* A minor Floatbox patch.
