Improved logic for intelligent asking when to save abstractions. No longer is it necessary to check whether to save an abstraction after it has been changes and only displaced on parent. this is because objects are "activated" when selected which potentially means that abstractions would be recreated as soon as they are deselected essentially making user lose anything they changed in the abstraction and did not save. However, in pd-l2ork we check when objects are activated whether their rtext (and therefore also its arguments) have changed and only recreate object if they did.
