fix issue #29: unconfigurable vserver on non-existant defaultchannel set
add generated slice php file for Mumble 1.2.4: Murmur_1.2.4.php
more descriptive debug msgs on adding error/warning, comment to $debug setting
check for Ice.php and Murmur.php, set ice_context on 3.4, robust createServer

* Check for Ice.php in include path and Murmur.php - on false, display error
* set ice_context in ice 3.4 as well (like on 3.3)
* make createServer() more robust (set ice_context)
* fix whitespace in ban()
from index: redirect to /user/ instead of /user
add translation strings for the two recently added errors
fix unbanning

* unbanning did not work anymore for IPv4 addresses. This has now been fixed by implementing an adequate conversion from ipv4 string to ipv6 bytearray
add fixed Murmur.ice of version 1.2.4

In this context, fixed means prepared for inclusion (php ice.slice
setting) without the need of providing the Ice/SliceChecksumDict.ice file.
Add comment for ice 3.5. Adjust default classfile to Murmur 1.2.4.
