[style] [fix] background images for camera photo-meta svg
instead of inline svgs
- one extra HTTP request per SVG
- no CSS styling (but that's fine)
- no repeated data in the document
- svg is maintained separately from HTML – replaceable with a single line of CSS per image
[edit] svg cleanup
[add] [config] syndication escape filter
[new] [config] &nbsp; escape filter
[config] [content] apply new filters to site Atom feed
for RSS reader compatibility
