Support new security model in the formSubmit function - bug fix

V5.14 8 Sept 2011  (c) 2000-2011 John Lim. All rights reserved.
  Released under both BSD license and Lesser GPL library license. 
  Whenever there is any discrepancy between the two licenses, 
  the BSD license will take precedence.

  Latest version is available at http://adodb.sourceforge.net
  
  Portable version of oci8 driver, to make it more similar to other database drivers.
  The main differences are

   1. that the OCI_ASSOC names are in lowercase instead of uppercase.
   2. bind variables are mapped using ? instead of :<bindvar>

   Should some emulation of RecordCount() be implemented?
