see tool file name issues when opening multiple files

[kluepfel]

1. >see a.extension a -> two files open, a and a.extension
2. Click on the window containing a.extension (should be behind the window with a)
3. Hit Command-S to save --> The file name in the save sheet is pre-filled with "a" Expected: Should be "a.extension"

This is probably resolved with #123 - can you recheck this on the 5.1 release?
