fix for passive parenting hack, it was not taken into account after transforming the object interactively

added a fake parenting for passive shards, those are simply moved with the object itself, so you can parent the entire object and have exact motion data in the passive shards

forgot to take some rigidbody settings into account during object conversion

fix for possible rotation glitch when converting back to objects

fix for Fracture Modifier to object converter (external mode), not all settings were taken into account, and object disappeared when not being on startframe, but as converting mid-sim yields unexpected results, still limiting conversion to startframe, added a notification for this

added dynamic threshold adaption in case of changing timesteps for plastic constraints, also enabling plastic constraints in case they enter plastic state now

fix for windows only: avoiding changing the global locale avoids slowdown in windows string operations

fix: spring constraints were not created properly while setting up the simulation

some more fixes to have proper plastic constraint support

fix for material assignment to meshislands, dont create unnecessary material slots any more

taking now all constraint properties into account when converting back to objects

partial fix, take proper constraint locations and rotations into account when converting back to objects, but todo, take own object transform into account too

added names for meshislands, can now convert back to named objects, added load / save support (was missing)

fixes for the monitoring logic of plastic constraints, again

fixes for correct rotation calculation in prefractured and external mode

used more exact angle calculation method for external mode, different formulae for tolerances, and some cleanup of obsolete stuff.

added material handling (so meshislands get correct materials from original objects) and added plastic tolerance values, which are taken into account with special simulation mode only.

reduced a performance bottleneck when adding many constraints in a loop, do not trigger modifier updates or set validate flags or even call bullet functions... but todo is to keep a useful update mechanism

avoid resetting cache (and iterating possibly through the rigidbody group) when adding mesh constraints

attempt to make mesh island packing faster when being called in a loop, create the dm only once after packing
