Include ID attribute in function.html_select_date.php

Hello,

I added support for inclusion of the ID attribute to
function.html_select_date.php that I believe might make sense to be
included in future releases.

Reason being that I use to add <label> elements for all fields in a
form and the HTML spec requires the <label for="elem"> to be
associated the the ID of a control.

In the version I am submitting the ID will only be included if it is
explicitly requested in the template by providing a value by addding
  {html_select_date ... id="string" ...
If the ID should be included by default it can easily be done by
changing the init default from null to a string (copy of $prefix for
example).

While at it I also made the <input ... for the year_as_text xhtml compliant.

(and to follow up on the private email I sent to monte: at first I
also included the addition of access keys to the select elements -
until I reread the specs and realized they are not supposed to be in
there. Duh!)

Richard
