Fix to image scaling JS so it doesn't allow superwide images.
Preserve scaled width/height on shrink, don't set both to max values.
Line height should have stayed 1em for payne tags.
Fixed broken Github repo link in footer
Applied vanilla 1.1.18 patches. (Will need to apply SSI.php manually or add to repo)
Merge pull request #74 from thunderrump/master
