* Removed AssetHttpServer, using BaseHttpServer instead
* Removed legacy REST handling * Created two custom IStreamHandlers for asset up/download * Removed quite a lot of double and triple encodings, trying to work towards binary only and direct write into storage. * Introduced BaseStreamHandler with GetParam() and some other goodies
