[Twisted-web] 2 small patches for livepage-completion-notification-3

hi! i have two small patches for the livepage-completion-notification-3 branch. the first one adds the possibility to set callbacks, which are called in case the livepage connection dies. it's basically what fzZzy told my on #twisted.web today. "<fzZzy> then, on line 35, do..." ;) the second patch adds a "prepend" helper method to ClientHandle. bye bye - sifu --- http://sifu.info
