decentralized directories: integration and testing

Browse Source 
* use new decentralized directories everywhere instead of old centralized directories
 * provide UI to them through the web server
 * provide UI to them through the CLI
 * update unit tests to simulate decentralized mutable directories in order to test other components that rely on them
 * remove the notion of a "vdrive server" and a client thereof
 * remove the notion of a "public vdrive", which was a directory that was centrally published/subscribed automatically by the tahoe node (you can accomplish this manually by making a directory and posting the URL to it on your web site, for example)
 * add a notion of "wait_for_numpeers" when you need to publish data to peers, which is how many peers should be attached before you start.  The default is 1.
 * add __repr__ for filesystem nodes (note: these reprs contain a few bits of the secret key!)
 * fix a few bugs where we used to equate "mutable" with "not read-only".  Nowadays all directories are mutable, but some might be read-only (to you).
 * fix a few bugs where code wasn't aware of the new general-purpose metadata dict the comes with each filesystem edge
 * sundry fixes to unit tests to adjust to the new directories, e.g. don't assume that every share on disk belongs to a chk file.
