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.)
