Greasemonkey 4.7 Release

The entire list of bugs handled in this release is also available via the 4.6 milestone on GitHub. If you are using this version and notice problems, it's best to let us know at greasemonkey-dev (and be clear that it's with this version).

New features:

• Automatic update support (#2531)
• Per-user include/exclude/match settings (#2728)

Warning!  For the first time, automatic updates will destroy local edits made since install time.  After that point, we track both install time and edit time and will not overwrite edits-since-install with new automatic updates.  Unfortunately we weren't tracking this information until the feature was added.
