RetroShare/plugins/FeedReader/gui/FeedReaderDialog.cpp
thunder2 148d1310a2 Added new button to open the link of the message in browser or copy the link of the message.
Added "RSS: " for the forum feeds.
Parse the feedburner:origLink in the rss feed.
Moved download functions to a new class CURLWrapper for easy use.
Added two new functions (currently only for local feeds for testing):
- embed images into the message (works for Qt 4.7 and higher)
- save complete web page
