This changes the pin behavior. It uses the filenames given through the api, and allows files to be streamed faltly (not a hierarchy), which is easier for other things (like vinyl in node-ipfs-api land). Files can also be entirely out of order, and the garbage intermediate directories will not be pinned (gc-ed later). The changes also mean the output of add has changed slightly-- it no longer shows the local path added, but rather the dag path relative to the added roots. This is a small difference, but changes tests. The dagutils.Editor creates a lot of chaff (intermediate objects) along the way. Wonder how we might minimize the writes to the datastore... This commit also removes the "NilRepo()" part of the --only-hash mode. We need to store at least in an in-mem repo/datastore because otherwise the dagutils.Editor breaks.
