Subject: net-p2p/py-ed2k-tools: add rudimentary support for TAG_TYPE_BLOB

While most common eDonkey2000's .part.met tags are integers and
strings, there could be other data embedded in them, like binary
data blobs.  Ignore (skip) them for now rather than choking on.

While here, use a better way to detect if supplied argument is
a directory.
