Bug #1118

Updated by pospelov over 5 years ago

* which includes catch of all exceptions from all models while reading 1.2 project file
** this exceptions arises due to disappearance of DEPTH from list of ParticleItem properties

* and creation of good looking import widget, which will explain the user, that nothing terrible had happened, his project was read almost successfully, and only some components (see list) might have screwed numbers (please check).

* Another problem to fix here: I can't open project file send by Marvin through internet, projectdocument.cpp strangely complains "wrong permission or binary file", although file looks normal to me.
