Implement user mode "x": hostname cloaking (closes: #102)
When a client has user mode "x" set, its real hostname is cloaked by substituting it with the server name (as configured in ngircd.conf). Restricted clients (user mode "r") aren't allowed to change mode "x". Please note that hostname cloaking is only in effect in server-client communication! The server still uses the real hostname for its own logging and for all server-server communication -- therefore all servers in the network must support user mode "x" to prevent older servers from leaking the real hostname of a cloaked client!
