This PR contains code removal that was implemented part of CRM-16189 i.e Contribute Settings for Close Accounting Period which is now moved into an extension.

I'm happy to merge this, @pradpnayak earlier explained that the fiscalYear setting was duplicated on that form & remains on the date settings form.

However, there is still one more place I found that needs to go - that can be a follow up

//CRM-16189
if (CRM_Contribute_BAO_Contribution::checkContributeSettings('financial_account_bal_enable')) {
  $this->add('text', 'opening_balance', ts('Opening Balance'), $attributes['opening_balance']);
  $this->add('text', 'current_period_opening_balance', ts('Current Period Opening Balance'), $attributes['current_period_opening_balance']);
  $financialAccountType = CRM_Core_PseudoConstant::get(
    'CRM_Financial_DAO_FinancialAccount',
    'financial_account_type_id',
    array('labelColumn' => 'name')
  );
