Update to version 0.9.11

IMPORTANT NOTE: This version does not include backwards support
                for the old style SILC private key so if you
                skipped 0.9.10 version you won't be able to run
                this client without generating new key pair.

Changes between 0.9.10 and 0.9.11
=================================

 * workaround a bug in GCC which causes memory exhaustion when
   compiling sha1 with optimizations on UltraSPARC.  from openbsd

 * Don't display "foo appears as foo\nYou're now known as foo"
   messages.
 * Do not print the nickname in SERVER_SIGNOFF if we do not
   have it.  Prevents asserts in Irssi core.  It is possible we
   don't have the nick if it was just being resolved when server
   signoff.
 * Prevent endless resolving of user informations in USERS
   command by checking the command reply status correctly.
 * Don't print signed messages when sending failed.
 * Send adequate signal when founding a channel by joing it.
 * Make GETKEY to update the client entrys fingerprint too.

 * Fixed autonick crashbug in client library.
 * Fix theme abstracts parsing.
 * Fixed double free in SKE library error hadling when signature
   error occurred.
