[PD] unit impulse without [dirac~]

[Roman Haefeli]

there is actually no need at all for doing a samplewise delay with [z~],
since you can schedule everything (also the startpoint) with [vline~].
you really only need a [vline~]. i just haven't time to make an example
patch, but i can make one in a few hours, if there is still need for it.
