update queue autopause option

The autopause option in queues.conf can be passed a new value, "all." The
result is that if a member becomes auto-paused, he will be paused in all
queues for which he is a member, not just the queue that failed to reach
the member
; Autopause will pause a queue member if they fail to answer a call
; no: Member will not be paused
; yes: Member will be paused only in the queue where the timeout took place
; all: Memeber will be paused in all queues he/she is a member
;autopause=yes
set default value for autopause to no
