Disabled buttons can still be clicked

[flightsurvey]

When the OK button is disabled because validation tests have failed it shows as disabled but can still be clicked on.

@flightsurvey add this code to validator.js

Line 294:

   Validator.prototype.toggleSubmit = function () {
    if (!this.options.disable) return
    this.$btn.toggleClass('disabled', this.isIncomplete() || this.hasErrors())
    // add this line
    this.$btn.attr('disabled', this.isIncomplete() || this.hasErrors())
  }

Line 327:

   this.$btn.removeClass('disabled')
  // and this
   this.$btn.prop('disabled', false)

This needs a PR! Been banging my head against the wall for an hour trying to understand this.

Adding this to the validator.js works well for me but the div below disappear <div class="help-block with-errors"></div>
