[web2py] XHTML markup validation nits

[weheh]

I am cleaning my XHTML through the W3C validation service and I'm
turning up a bunch of web2py XHTML that doesn't pass validation.
Mostly nit-picky stuff like <script> instead of <script type="text/
javascript">. Since some of this is embedded in web2py, like the
recaptcha for example, it seems like it should be cleaned up in the
web2py source.
