ted v. 2.8.1

• This release fixes a long-standing bug where very rarely file contents would get screwed up after an automatic reload. I'm still not sure how that could happen- seems like it must be that the file is edited without its modification time getting updated? Now we use inotify on Linux (in addition to mtime) to fix this. I haven't had this issue on Windows, so this is a Linux-only fix, but it should be possible to use FindFirstChangeNotificationW on Windows if needed.
• Reloading file from disk no longer clears undo history (you can now undo the reload).
