I've been through the template files and I think some of them are not used anymore.

gui/templates/storage/dataset_ok.html => not used, message returned via json

gui/templates/submenu.html => old mock-up
gui/templates/sidemenu.html => old mock-up

gui/templates/storage/disk_form.html => the form action is not valid anymore (since r5890) and is not used

gui/templates/registration/password_change_done.html => did not find where it is used
gui/templates/registration/password_change_form.html => did not find where it is used
gui/templates/registration/register.html => did not find where it is used

So if they really are not used, maybe they could be removed from the svn repository (svn rm).
