Get asset_hash working after the sitemap refactor. Part of this required changing the behavior of the OnDisk Sitemap extension to rebuild the sitemap every time a file is touched, instead of just when files are added (even if the file being touched is ignored by the sitemap, like a partial!). This is because asset_hash needs to recalculate hashes whenever any file changes, since partials can affect the output of other files.
