Fixes #184; request server file list batching

The request server needs to support batching of file list requests. To
address this the methods LsSave(string) and LsNext()string are added to
the Request object. They should work to store a token to keep your place.

The Handler should now return an EOF when the end of the directory list is
reached. If it doesn't but returns an empty list, the wrapper will send the EOF
for you.

The old behaviour of just returning 1 batch and sending the EOF is preserved if
you don't set the token (you don't use LsSave). It will return the 1 list and
EOF on the next underlying readdir call. This is to preserve backwards
compatibility and it not the recommended way to handle file lists.
