InterCom_userapi_createhook wrong return value

[hvorragend]

bug description

InterCom?_userapi_createhook function returns wrong value
at the end of the function there is

return true;

bug analysis

in the pnModCallHooks function the hokks are called sequentiell and the return value (extravalue [the name of the module]) from one hook is put into the next hook as arg value.
fix recommendation

the return value must be

return $args['extrainfo'];
