Update German Localization
Improved fix for #3889 (Middle click should close files):
- Don't go through normal selection-click handling codepath first: detect
middle click in the same place we filter out close-button clicks. No longer
need a separate click listener as a result.
- Use constants for event.which
- Remove long-commented-out rename code
- Move misplaced comment ("might never have been opened") to its rightful
home
