UEnvGen refine controls, scaling factor
finishing up EnvView

example:
x = EnvView( env: Env({1.0.rand}!10, ({1.0.rand}!9).normalizeSum * 10,
0 ) );
small tweak to EnvEditView
UEvent:renderNumChannels can now be a function

this enables WFSCollider to check the current previewMode and return
numChannels accordingly
adding range slider to EnvView
fix document opening for SCIDE, thanks Marije!
larger DragSink for adding Udef to empty chain

or to end of chain
correct examples for USession and UScore
make UnitRacks and on-the-fly Udefs visible on qt
make bounds for CodeSpec:makeView depend on view width

thanks Marije!
MassEditU: include mode for ArgSpecs
unit packing: 1st step (experimental!!)

setting UChainGUI.current.packUnits = true will pack any series of
units with equal defs in the chain together in a MassEditU. This
functionality is not finished yet!!
UChainGUI '+' button auto-increase i/o buses

when hitting the plus button, the new unit that is added to the chain
will be connected to the next bus(es) by default
change mass edit behaviour for ControlSpec

if all values are the same, dragging the range slider now creates an
interpolated line across all values, so that the min and max are always
correct.
add massEditWindow to UChainGUI

the ^ button opens a new window with all units of the MassEditU in it
finishing up and enabling UChain:packUnits
show dragging areas for units in between in UChainGUI

perhaps this makes it easier to drag and drop on Qt
smaller addLast box

easier on the eyes
move GlobalPathDict @resources to GlobalPathDict:initClass

so that it is available even if ULib.startup hasn't been called yet
add multi-load button to BufSndFile MassEdit
