[Dchub-announce] dchub 0.5.0 released

[eric]

Changelog:

* support both libgcrypt (>=1.1.12) and openSSL as cryptography library.

* new key added: LOCK_MODE. It allows negation of LOCK_PATTERN handling. If 
not set or set to 1, LOCK_PATTERN denies access to user matching the lock 
pattern. If set to 2, LOCK_PATTERN denies access to user not matching the 
lock pattern.

* new event added: kick. Patch #1782. It occurs when a user is kicked.

* new event added: ban. It occurs when a user is banned.

* Lot of changes in the kick/ban command set. Only the following commands 
exist:
    -kick
    -skick
    -ban
    -banlist
    -unban

  And they are all cluster compatible.

  Note: this requires a cluster running at least the same version. If the 
cluster is older, it will just ignore the command.

* new event added: hubinit. It occurs before the hub enters into the main 
loop.

* remove inaccurate use of removed command (-tbanip). Patch #1846 by Dirk 
Rieger.

* update ext_prog toolkit to support the new ban function. Patch #1847 by Dirk 
Rieger.

* ClientBot updated, #seen and #users added. Properly handles NMDC v2. Patch 
#1851 by Dirk Rieger.

* Fix a skick crash problem occuring when skick is used without reason.

* rewrote the -ban the command (doesn't kick the user anymore) by Yves 
BLUSSEAU.

* ban by IP address now work even if the user is not connected. (Yves 
BLUSSEAU).

* Don't allow connection with empty nickname.

* added #msg & #clearmsg command to ClientBot. Patch #1938 by Dirk Rieger.

* add ban by IP in cluster mode.

* add the --enable-dmalloc option in configure. (Yves BLUSSEAU).
