- Added error handling to xml functions - Added xslt transformation - Added retransform of existing messages - Redesigned preview dialog - Enabled embed images for forum feeds - Changed config format, switching back to an older version results in a loss of all data of the FeedReader Added new base class RSPlainTextEdit with placeholder text. New library libxslt needed git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@6081 b45a01b8-16f6-495d-af2f-9b41ad6348cc
