migrated model swapping to mvc and made Model::swapObjects to emit dataChanged signals as a temporary solution

removed some unneeded headers

Finally removed the cancer that is the LDObject::model pointer

Added LDObject serialization and refactored the internal resource managing to use it. No more tearing objects from one model into another, and this provides a stable way to keep an object's state in memory such as the edit history.

fix warning

removed another LDObject::model() use

removed LDError::fileReferenced

reimplemented detection of broken references in PartDownloadRequest::downloadFinished
