Bug 511456

SUMMARY

I really like the feature to open several PDF files in one Okular instance with multiple tabs as opening them in new windows easily clutters my desktop. Sadly I cannot make this the default as `okular` is also used when I open a PDF from `mutt`: `mutt` saves the PDF to a temporary file and then invokes `okular $tmp.pdf` and waits for that command to return. When the "Open new documents in sub window" is enabled, that command returns immediately if another instance of Okular is already running. `mutt` den deletes the temporary file and Okular is left with nothing to display.
Sadly there also is no inverse of `okular --unique` which `mutt` could use the get a new instance.


STEPS TO REPRODUCE
1. Launch Okular
2. Go to "settings" / "Generel" and enable "Neue Dateien in Unterfester öffnen"
3. In a shell: ```tmp=$(mktemp --suffix=.pdf); cp Some.pdf "$tmp"; okular "$tmp"; rm "$tmp"```

OBSERVED RESULT
 
If Okular is fast enough, it will succeed to open the PDF.
Most often it will fail.

EXPECTED RESULT

1. Running `okular` from the command line should have an option to wait, until the document is closed or Okular exits.
2. The should be an option in the "Open..."-dialog to open documents in tabs if the option is turned off.
