RetroShare/libretroshare/src/serialiser/rsdiscitems.cc
drbob 5e41b21cef Lots of bugfixes and tweaks: 
* Switched p3Ranking to share Friends Links as well as own.
 * Modified rankmsgs to contain source id.
 * Fixed up rsNotify, added pqiNotify and global function call to get it.
 * Added notify for Bad Incoming Directory
 * Added Emergency Incoming directory so RS can keep running.
 * Added notify for Bad Packet (connecting to V0.3.X)
 * Added notify for Incomplete Packet Read (not been triggered yet!)
 * added close() to BinInterface, close on pqissl calls reset() 
 * removed exit(1) calls from pqistreamer, replaced with bio->close().
 * Increased Maximum Packet Size for HTML messages.
 * Fixed Online/Offline Message Forwarding. (TEST).
 * Increased DHT bootstrap buckets to 4.
 * Cleaned up much of serialiser debug (was slowing down Mac)
 * Added directory path to File Listings.
 * added ConvertSharedFilePath() so correct local dir can be found.
 * Added ForceDirectoryCheck() and InDirectoryCheck() for file hashing.
 * removed old TMP cache loading.
 * switched off Cache debug.
