This reverts commit 0ba13491e50d67360d0ed9e2e77dc8095994b8fd.

DG MS; added checkboxes for services in the new publisher (currently not working) / user presenter contains services	

This adds an error message to the mobile version of the login page
for failed logins, as requested in #3048

This (along with the standard login page) appears to use the Devise
i18n for the error message, which may need to be updated to reflect
the fact that we're not using email addresses for authentication.
