Version 0 cookies support

          When using the <code>org.apache.tomcat.util.http.ServerCookie.VERSION_SWITCH=false</code> property, cookies           containing characters <literal>\</literal>, <literal>(</literal>, <literal>)</literal>, <literal>:</literal>,           <literal>&lt;</literal>, <literal>=</literal>, <literal>&gt;</literal>, <literal>?</literal>,           <literal>@</literal>, <literal>[</literal>, <literal>\\</literal>, <literal>]</literal>, <literal>{</literal>,           <literal>}</literal>, <literal>(</literal>, <literal>:</literal> were truncated to the first occurence of one of the listed characters. Changes have been made to the way these characters are handled in the code which prevents cookies containing these characters being incorrectly truncated.
