htdocs: Update package versions

  checkboxes.js            1.0.6   1.2.2
  clipboard.js             1.7.1   1.7.1
  jquery                  1.10.1   3.6.0
  selectize               0.11.2  0.13.5
  sticky-table-headers     ?.?.?  0.1.24
  tablednd                 0.4.0   1.0.5

Amazingly, the only functional change required here is to add an
additional piece of code to re-enable shift-select [1]. This is
otherwise a straight swap.
