feedlink/blogpost templates: use class instead of id There can be more than one feedlink group in a page, as well as (more rarely) multiple blog forms, and using the same id for all of them causes HTML validation errors. Replace the id with a class by the same name and adjust in-repository CSS.
inline: pass the Atom/RSS titles to the templates The default templates are also updated to make use of this information. The rel="alternate" attribute is also inserted, for completeness. (cherry picked from commit 618ade535e6a7967a510d9e210edaef3d37cc9bc)
use cgitemplate, remove misctemplate
add cgitemplate cgitemplate is a modified misctemplate that takes an optional cgi object and uses it to set the baseurl, and also optionally the forcebaseurl, if a page is provided. If no cgi object is provided, it will fall back to using $config{url}. I expect this will only be needed in exceptional cases where that doesn't much matter, such as cgierror(). showform uses cgitemplate, so there is no more need for showform_preview.
better handling of relative permalinks This way, do=goto will go to the page relative to the current location, while the permalinks in feeds will be absolute (unless an url is not configured at all).
