Publ v0.5.10 released

Publ v0.5.10 is now available. The following has changed since v0.5.9:

• Image sets will generate fullsize renditions (and their links) for images which were skipped, so they will still appear in the lightbox
• Footnotes now get rolled up into the entry.more (with some caveats), and also get stable permalinks for their references¹
• You can now annotate an HTML attribute with $ to force it to resolve as an asset (useful for certain JavaScript libraries); see the relevant documentation

I’ve also made a bunch of changes to the sample templates.
