issue2551391 - checkboxes and radiobutton inputs get wrong id's.
Actually it breaks automatic id assignment for all inputs.
Inputs now get an automatic id assignment that matches the name.
It can be overridden by supplting an id parameter in the call to
the field() method.
This is also a partial fix for issue1513369. I think it obsoletes the
changes to templating.py.
