Identical to OpenChemistry/avogadrolibs#1206

To Reproduce
Steps to reproduce the behavior:

2. Don't save it yet
3. Click open

6. Opened file is displayed in new entry in "Molecules" view, original, unsaved molecule is not lost

Get prompt to save with the warning that your changes will be lost if you don't

While the wording is perhaps off, I still think this is a good idea to prompt for a save.

But why? There doesn't seem to be a risk of the current molecule being lost, and no other program that I know of works in this way...
