[RFC][icedtea-web]: Small fix for PR1189 w/ reproducer

[Saad Mohammad]

Hi Adam,

Sorry for the late follow-up. I see a lot has changed since the last patch -
please take a look at the updated patches attached.


*Note*

As I mentioned earlier on IRC, Google Chrome does not launch applets that do not
have a code attribute defined. This is rather unfortunate as the main-class name
can be found within the jnlp file, if jnlp_href is used.

As for Firefox, however, there is no dependency on the code attribute to
continue launching the applet. Just like the proprietary plugin, we should also
avoid the dependency of the code attribute if the information can be found
elsewhere. In cases where the jnlp file is missing the main-class attribute, it
will lead to a ParseException resembling similar behaviour of the proprietary
plugin since it's a requirement in a jnlp applet file.
