#231 Add support to provide SSL certificates in byte array form

[Marcelo José Garcia]

Add support to provide SSL certificates in byte array form to WebClientOptions.setSSLClientCertificate.
Currently it only supports certificates in URL form.
The new feature would make possible to load certificates stored in database fields for instance.
If it's accepted, I can submit the patch I've already done.

Thanks for reporting and for the patch, modified version commited in SVN.

Some hints:
* InputStream is more generic than byte array
* No need to format other parts of the code

[Marcelo José Garcia]

You're absolutely right about InputStream.
HtmlUnit is very important on my project and was great be able to contribute, even this small contribution.
Thanks!!!
