sprint 43 - czech language

updated
Fix bug #9096 (No error messages when dragging invalid files onto Brackets) -
The split view changes made pre-open filtering of dropped files stricter.
But actually, filtering of drag & dropped files isn't needed at all now
that images can go in working set -- so just remove it.

Fix bug where legacy DocumentManager "currentDocumentChange" was fired
needlessly for null->null cases. Fix stale docs for this event.

Re-enable most of the image-preview unit tests in DocumentCommandHandlers-test,
since that feature is implemented again. ("currentDocumentChange" fix fixes
the one test that wasn't already passing).
