Resolve several bugs that are probably as old as Tracker itself:

1) Move To now works as advertised in all cases - previously it silently converted a move into a copy if the destination volume was different, as its move code was not geared towards handling that case properly. This also has the side effect that drag and drop is now always a move as well unless overridden via right click DnD. This may or may not be reverted back to the original behavior later depending on the consensus. 2) Copying a folder onto another folder of the same name now merges the contents instead of destroying the original. This fixes ticket #1420. Still to do: interactive prompting to allow fine grained file replacement and skipping in this and other multi-file cases, but I'll open a new enhancement ticket for that. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28731 a95241bf-73f2-0310-859d-f6bbb57e9c96
