[jdom-interest] DOMAdapter propose

[Eugene Karpov]

I've a propose to add getDocument(java.net.URL url, boolean validate) method 
to DOMAdapter interface.

So, if original parser permit using URL as input, it will make possible to 
use relative URLs for system DTDs and ENTITIES. Otherwise, it will always 
possible to convert URL to InputStream.

With current DOMAdapter interface I could not use relative system DTD path 
for XML and corresponding DTD stored in JAR, cause it can not be described in 
terms of java.io.File.
