hipchat bug fix

the current implementation of the hipchat notification types
 is buggy on updates because it never sets previously enabled
types back to false if they are not specified in the yaml anymore
but were once true.also room can be blank so it will use the default
room as configured in the master jenkins configuration
also standardize the notify-* arguments even if jenkins plugin
is bad about it
