VCV Rack modules 0.5.4 release

Code fixes on TinySawish and BPM Clock, added CV inputs for each parameter of the Phaser module.
Exposed 16-step Seq trigger modes into the panel so nobody misses them. (Contextual menu is there, but won't change the settings, you have to use the panel switch).
New Mono VU meter, because everybody likes lights!
New Steps module, based on Mental's Counters module but with 3 counters and up to 64 steps each one.
New SuperDrive module, overdrive Fx for those acid bass lines we all love!
New Reverb module, based on ML_Modules, a bit tamed reverb and blend knob to get a mixed audio signal right from the module.
Also all the FX modules got a new look, to match the new SuperDrive module look
