Since it's all creations in this changeset, you can simply download
the changeset from
http://www.openstreetmap.org/api/0.6/changeset/2354740/download ,
replace the <create> tag with <delete> and upload using
http://www.openstreetmap.pl/balrog/bulkupload/upload.py

It'll probably fail with error 500 because there are so many elements
and the server seems unstable, so you can split the changeset using
http://www.openstreetmap.pl/balrog/bulkupload/split.py and upload in
reverse order, it should still be much quicker than using the revert
tool.
