- Update year on LICENSE.txt; add, "All rights reserved."
- Add self to copyright notice and license (privately authorized).
- Add '\n' to last lines of files missing such.
- Remove a.m.o. metadata.
Files from the 1.0.8.6 xpi were missing '\n' at the end of their last
lines. Changing this would invalidate the Mozilla manifest/signature
data, so I removed that.
No substantive code changes in this commit.
