// autoComplete (text_input, select_input, ["text"|"value"], [true|false])
//   Use this function when you have a SELECT box of values and a text
//   input box with a fill-in value. Often, onChange of the SELECT box
//   will fill in the selected value into the text input (working like
//   a Windows combo box). Using this function, typing into the text
//   box will auto-select the best match in the SELECT box and do
//   auto-complete in supported browsers.
//   Arguments:
//      field = text input field object
//      select = select list object containing valid values
//      property = either "text" or "value". This chooses which of the
//                 SELECT properties gets filled into the text box -
//                 the 'value' or 'text' of the selected option
//      forcematch = true or false. Set to 'true' to not allow any text
//                 in the text box that does not match an option. Only
//                 supported in IE (possible future Netscape).
