disable 'canInsert' for certain UMapDefs

for these it is not logical or convenient to use the previously set
value automatically.
correct comments on clip_point
enable sc3.7 compatibility
add 'lag_point' UMapDef

this can replace the 'pointLag' parameter of the dynamic panners
use 'lag_point' in default presets
hide 'pointLag' parameter from dynamic parameters

this is now a depricated parameter, to be removed from the synthdefs at
some point.
add 'shared_in_point' and more
removing ULink and related
subdivise 'point' category
add 'point_to_value' UMapDefs

we can convert angle, speed, distance and axis of points and
trajectories to values for unit parameters
add 'point_in_rect' UMapDef
step two in deprecating pointLag and pointFromBus
use bus mapping for dynamic wfs array levels

simplifying the synthdefs
make arrayRollOff and arrayLimit static in all cases
remove pointLag and pointFromBus
remove unused wfs panner synthdefs
remove unused 'uni' mode from wfs pre-panners
remove 'lag' setting from trajectory umaps

lag_point can now easily be inserted separately
hide 'pointFromBus' for furseDistanceFilter
change shared_point i/o UMapDef names
