allow the introducer to set default encoding parameters. Closes #84. By writing something like "25 75 100" into a file named 'encoding_parameters' in the central Introducer's base directory, all clients which use that introducer will be advised to use 25-out-of-100 encoding for files (i.e. 100 shares will be produced, 25 are required to reconstruct, and the upload process will be happy if it can find homes for at least 75 shares). The default values are "3 7 10". For small meshes, the defaults are probably good, but for larger ones it may be appropriate to increase the number of shares.

extirpate all references the "queen" and "metatracker" This is a potentially disruptive and potentially ugly change to the code base, because I renamed the object that serves in both roles from "Queen" to "IntroducerAndVdrive", which is a bit of an ugly name. However, I think that clarity is important enough in this release to make this change. All unit tests pass. I'm now darcs recording this patch in order to pull it to other machines for more testing.

rearrange service startup a bit, now Node.startService() returns a Deferred that fires when the tub is actually ready, and there is also a Node.when_tub_ready() hook. This allows get_local_addresses() to be slow and not break everything. Changed all necessary test cases to accomodate this slow startup.
