Committing patch from Juerg Lehni:

* Add String getContent(String encoding) method to Resource interface.
* Propagate IOExceptions in FileResource.getContent().
* Make FileResource.getContent() more robust by not assuming all data can
   be read in one single blow.
* Do lazy byte->char conversion in ZipResource.getContent() in the String
   constructor rather than a Reader.
