Bug #89405	Show warning when saving EER diagram file that has been modified outside

Description:
When saving an EER diagram in mysql workbench, it simply overwrites the file. This overwrites changes that other people did in the meantime since opening the file, e.g. when the .mwb file is on a network share.

To allow multiple people editing the same file, workbench should tell the user that the file has been modified outside and let him confirm that he wants to overwrite the file with his changes.

How to repeat:
1. User1 opens .mwb file on network share
2. User2 opens the same .mwb file on network share
3. User2 changes something, saves
4. User1 changes something, saves

User1 overwrote User2's changes.

Hello Christian,

Thank you for the feature request!

Thanks,
Umesh
