Remove mechanism for catching proc_pidinfo and statfs timeouts. It was causing crashes, but I don't understand why. Perhaps mixing ARC and non-ARC code has some problem? I saw lots of crashes on 3.1.4 where proc_pidinfo exceeded the timeout and when it finally returned there was heap corruption. It looked as though the dispatch group had been freed even though there was an outstanding reference to it. At any rate, if proc_pidinfo is hanging you're going to have a bad time even without this workaround.

Prevent statfs from hanging the app for more than half a second in the face of broken network filesystems. Issue 6110

Avoid filesystem access to network mounts by semantic history. fileURLWithPath: and standardizedURL would both perform I/O. Issue 5740.

Give the user the option to append or replace log files. Remember the last used directory for the logfile save panel

Move source into sources/ directory. Delete a few unused images in the process and fix a reference to an Aqua image in FindView

Fix bug where tools would become broken after becoming too short. Add Notes tool. Alphabetize tools. Add NSFileManager+DirectoryLocations.
