big ol' update to strip out the singletons, replacing them with

Browse Source 
a rooted app context.  The core itself has its own I2PAppContext
(see its javadoc for, uh, docs), and the router extends that to
expose the router's singletons.  The main point of this is to
make it so that we can run multiple routers in the same JVM, even
to allow different apps in the same JVM to switch singleton
implementations (e.g. run some routers with one set of profile
calculators, and other routers with a different one).
There is still some work to be done regarding the actual boot up
of multiple routers in a JVM, as well as their configuration,
though the plan is to have the RouterContext override the
I2PAppContext's getProperty/getPropertyNames methods to read from
a config file (seperate ones per context) instead of using the
System.getProperty that the base I2PAppContext uses.
Once the multi-router is working, i'll shim in a VMCommSystem
that doesn't depend upon sockets or threads to read/write (and
that uses configurable message send delays / disconnects / etc,
perhaps using data from the routerContext.getProperty to drive it).
I could hold off until the sim is all working, but there's a
truckload of changes in here and I hate dealing with conflicts ;)
Everything works - I've been running 'er for a while and kicked
the tires a bit, but if you see something amiss, please let me
know.
