hide the distinction between WAD and File from ES

instead, leave all the management with the NANDContentLoader.

for file data (directly on the NAND), this opens the file on-demand and
returns the requested chunk when asked for it.
for on-the-fly decrypted WAD data, we just keep the decoded buffer in
memory, like we've done before - except that we don't give away any objects
we don't want to.
