Detect concurrent usage of the same project file #137

Hi all,

there's a problem if two users open a project file and both make changes and 
save the project.

When both users save their changes the change of the first user will be 
overwritten by the second user --> data loss.

Possible workarounds or fixes:
1. if the file on the disk has changed, the user should be prompted whether to 
overwrite the file or save the project at a different location.

2. only allow one user to open the file in readwrite mode. The second user 
should only be able to open the file readonly.
