drbob 8e3e7d5209 Cleaned up rsPeers to remove 10 minute reconnect. The reconnect was caused by
the periodical call of cleanupUsedLocation, which was reloading all the GPG Keys - for each cleanup Key.
This required cleaning up various bits (AuthGPG, rsPeers, p3Disc).

 * moved rsPeer::cleanUnusedLocations => p3PeerMgr::removeUnusedLocations();
 	- made the function light-weight, no loading of GPG Keys.
 * moved getSSLCertsFromGPG() fn from rsPeers => p3PeerMgr
 * added p3PeerMgr::removeAllFriendLocations() to cleanup when removing a GPG Friend.
 * cleaned up rsPeers, made addFriend() / removeFriend() universal functions.
 * remove bool   p3Peers::setAcceptToConnectGPGCertificate(const std::string &gpg_id, bool acceptance)
 * removed all Dummy SSL Ids. - There is no need for this!
 * Major changes to p3disc to correct FLAWED logic.  (needs more testing).
 * removed as many dependancies on retroshare/rspeer.h as possible.
 * changed p3turtle dependancy on rsPeers ==> mLinkMgr.
 * added p3LinkMgr::getPeerName() and p3PeerMgr::getPeerName()
 * added return 1 to pqissllistener::closeConnection().
 * removed unused code from AuthGPG().
 * removed storeAllKeys() calls in AuthGPG::AllowConnection().
