Create validiation code for the condition

At line 184

/**
 * Condition set the limit validation function
 */
function node_limitnumber_rules_condition_limit_validate($form, $form_state) {
  // TODO Move number checking code here
}

and line 240

/**
 * Condition set the Comment limit validation function
 */
function node_limitnumber_rules_comment_limit_validate($form, $form_state) {
  // TODO Move number checking code here
}

There needs to be some code that will validate the user supplied data. Probably could create one function to do both.
