#214390 by shrop. Partial backport of #153998, use a separate permission for blogapi since it does not depend on blog module.

Backport from HEAD.

- Patch #92992 by webchick and neclimdul: clean up documentation that is superseded by the new 'by module' administration dashboard.

- Patch #98688 by greggles: string cleanup.  Follow RFC2606 and use example.com for domain name examples.  Core uses that consistently so make sure your contributed modules do too.

- Patch #77919 by chx, eaton, moshe, et al: enable programmaticaly submitted forms via the pull model.

See: http://drupal.org/node/64279#t-placeholders

- Patch #78806 by James: moshe brought to my attention that the blogapi RSD was giving preferred treatment to bloggerapi - since we actually support much more feature rich apis (namely movabletype's) ... this patch gives the preferred treatment to MT. Also, it removes the unused "XML-RPC engine" setting - which wasn't being used anyway. And, since, any of the 3 API options will work regardless, this setting is extraneous.

   + reorganized ?q=admin/settings
   + deprecated the _settings hook

- Patch #33747 by Ber and Moshe: bugfix + code improvement: clean up some of the taxonomy loading code.
