Title:
  Problem with divide by zero when setting pagination limit

Status in Mahara:
  In Progress

Bug description:
  For certain blocks there is the ability to set the 'count' (pagination
  limit) and if one sets it to a non integer value it causes the error:

   [DivisionByZeroError]: Modulo by zero

  We need to set a rule for the field so that it can only be an integer, eg
    'rules'        => array('integer' => true, 'minvalue' => 1, 'maxvalue' => 100),

  To test:

  1) Create a plan
  2) create some tasks
  3) Edit a page and add plan block to page

  view page - all is fine

  4) Edit the plan block and set 'count' to 'none'

  On save - things hang
  On page reload - see error

  Can't edit page to fix problem so will mark this bug as high
