Added new reader (to read elements in parts)
Remove EAdResources (an all its implications)
Bundles now are handled with strings. I replaced EAdResources by a Map<String, Map<String, AssetDescriptor> (Map with bundles with maps with asset ids and asset descriptors). This simplifies a lot writing/reading.
Improvements in new reader
