[Tei-council] Stylesheets v7.46.0 released

Dear council, Syd and I, with the help of Martin Holmes and Peter Stadler, have just completed a new release of the stylesheets v7.46.0. In the process, we've also made a couple of updates to tcw22 and the utility script tei-install.sh. I don't know if stylesheets releases need to be announced on TEI-L, especially since we don't assemble a document listing changes besides a generated changelog. The freeze on the dev branch is now over, code away. Raff
