fixed bug with saving template visibility

Fix for providing a text alternative for tooltips for assistive technologies. ...

The fix consists of adding the current tooltip text to a <em> tag with the bootstrap class
sr-only that is made only available to assitive technologies.

Fix for issue #2174.

Enable spellcheck for text fields: ...

Changes:
 - added HTML 5 attribute spellcheck= "true" to text_field tag by adding
        spellcheck: true.
 - Did not add this attribute to text_fields for:
    firstname,
    surname,
    principal_investigator_name &
    data_contact.
   (it is irritating for folk to have a spellchecker say your name is incorrectly spelt.)
