Notification sometimes hangs and does not disappear

[GoogleCodeExporter]

f course - I thought already it would be too few information I've sent to you.
So, here we go:
        - OS: Linux (Ubuntu 11.04)
        - Eclipse (Juno - 4.2.1)
        java version "1.6.0_27"
        OpenJDK Runtime Environment (IcedTea6 1.12.3)
(6b27-1.12.3-0ubuntu1~12.04.1)
        OpenJDK Client VM (build 20.0-b12, mixed mode, sharing)

Procedure is:
- Create two diagrams
- Change in both files something
- say save all
In active diagram window (in my case) remains the notice
"path/file.uxf saved" until window is closed.

Another way to reproduce it was opening 2 diagrams quickly (the current 
notification would not disappear)

Problem was:
Notification was a singleton. now every drawpanel has its own notification.

fixed in r513
