thunder2 ef49000b9a FeedReader:
- 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
