monitor: fix reported event rethink a bit which event are reported and when. - drop 'toggle' event as it's not useful; now 'amused toggle' will report the play/pause event. - replace 'flush' with 'load'. there's no real difference between a flush and an empty load. (also, less event the better) - some events (next/prev/jump) are reported earlier to avoid possible issues (when messing around with the playing queue we can end up in every possible state.) - report 'seek' only after it really happened (i.e. after the player process sent the new position.) There's still a possible race here (we can receive a previous IMSG_POS and think it's the reply to the seek) but it it's hard/impossible to work around. - drop 'restart'. we have 'seek' now which is better (and actually restart is implemented on top of seek.) - add 'seek' to the default list of events.

amused-monitor: no need to list all the events `amused monitor' defaults to report all the events, that should be enough.

refactor control_notify it's awkward to call it with the address of the imsgev struct inside the ctl_conn struct. Just relay the info to every client in monitor mode. After all, if a client is in monitor mode *and* issues commands, it's not strange that they're echoed back (note that this is currently impossible, the command line client can either issue commands or be in monitor mode.)

amused-monitor: add a round function and simplify some bits

amused-monitor: drop unused `min' function

amused-monitor: rewrite excerpt function instead of passing "half" of the context wanted, just take the number of lines wanted. switch to a circular buffer to store the lines instead of shelling out (badly) to grep -C.

initialize status_format early in the main() otherwise we may leave it NULL (it's set only in ctl_status) and crash in print_status.

handle when the duration is zero

fix some leftovers better to use a control variable rather than `last' from a subroutine

add amused-monitor: an ncurses tui written in perl

document status -f

allow to customize the output of amused status This add a -f flag (that falls back to $AMUSED_STATUS_FORMAT) to control which field to print and in which order.

explain better non-regular/unknown files are treated
