Fixes two problems in the current group chat:

- the parser fails to embed two links in the same sentence
- the parser can potentially put smileys in the middle of <a> tags

Solution:
Since the message is in HTML, it is parsed into a DOM tree, then that DOM tree
is traversed and only the text nodes are parsed (see HandleRichText.cpp for
details).

Bonus fixes:
- missing std:: for endl (which was falling back to its Qt counterpart)
- commenting useless code in PeersDialog::smileyWidgetgroupchat()
- replacing int by size_t
- RetroShare.pro now queries gpgme-config for its include path
