div.messages ul has been added to the list of elements that shouldn't get a default margin-bottom of 1.5em. (It made the error messages look ugly.)

This is a bug fix update of Footnotes. The newly introduced feature to have multiple footnotes point to the same reference in Footnotes 6.x-2.2 unfortunately broke Footnotes when used with Views, or when Footnotes appear also in the teaser. Due to not resetting a variable between runs, some footnotes would end up missing (for instance on all Views pages except the first one).
