File Saving Prompt Provides Insufficient Information When Working With Multiple Scores

When saving multiple files, MuseScore does not show the file being saved. This is bad because the user has no way to tell if the changes need to be changed or not.

It is also easy to accidentally click "Discard" for the wrong file because the only thing that changes is the text in the save prompt.

Possible Fixes:

1. Automatically show the MuseScore staff in question when displaying the save prompt. For example, if the user will be prompted to save files A, B, and C, then when the prompt for A appears, A's staff should be visible.
2. Show a few bits of the score in question in the save prompt like the "Copy File" screenshot in the official Windows Desktop Apps Design Guidelines at https://msdn.microsoft.com/en-us/library/windows/desktop/dn742470.aspx.
3. Do both 1 & 2

I've included a screenshot to show the status quo.
