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):

- save complete web page
