[PD] slop~ (new object for 0.50) and the "slew" term

Slop~ _can_ be configured to be a slew limiter, or a linear low-pass filter, or
various other things - the name tries to convey that its identity is
in the eye o the beholder.  My intention was to design the most flexible
nonlinear one-pole filter I could.

But I think your "slew" object probably does need a more exact name :)
