[reference] Rewrite assets_version_format docs and add tip for path prefixing

Versioned path prefixes are useful for CDN's that do not support cache-busting via query strings. This seemed small enough to add as a tip, although it might be better expanded into a cookbook article (and this tip reduced to a "see cookbook" link).

Also added a note about required escaping of percentage signs in the option value.

[reference] Removing requirement for sqlite - no longer needed in 2.1
[reference] Add documentation for assets_base_urls option

I decided to gloss over the details of how a single base URL is selected from a collection when generating an asset's path, as the internal behavior of UrlPackage is just that.
