2e789e34e7 enforce range of HP/LP 
We must not assume that the host sends values within the the range
nor that the enum is always an integer.

2e933a6414 Fix a typo in HiAndLowPass.lua 
Instead of mixing two consecutive biquad orders with a linear xfade, the
code used the same weight for both signals to mix, due to a copy-paste
blunder. Brown-bag fix this now. Also change a little the threshold for
using 32-samples chunks to cater for steepness jumping from 0 to 4 (this
doesn't change anything for commonly used rates and is just for
robustness in never-happening cases anyway).

1dcb54ba22 Optimize a-HiAndLowPass 
- Better formula for the lpf smoothness parameter. It is computed only
  on init and rate change anyway...
- Only run as many Biquads as needed to save computing power, esp. when
  using low steepness and parameters are not changing.

30240b33e9 Make MIDI monitor a pass-through for audio and midi 
MIDI monitor only accepted midi data and output that same data. That was
logical for a MIDI plugin, but a consequence is that automatic pin
configuration makes MIDI monitors opaque to audio data, which means
drag'n'dropping a MIDI monitor for debugging purposes can suddenly cut
audio, or even change the channel count if strict I/O is enabled.

Improve the MIDI monitor so that it passes through all incoming data
unchanged.

1f08503ada Add a new MIDI monitor plugin 
This plugin lets through all incoming MIDI events, and also shows the
latest ones in a human-readable format directly on the mixer strip. The
user can choose the font size and the number of recent events displayed,
as well as whether to print values in decimal or hexadecimal, and
whether to print system events.
