not clearing the interrupted flag, seems smarter
beginning to move the notion of the filesystem locations into a new set of components
abstracting application structure

this is a combination of several changes, roughly explained below.  the changelist is huge, I know

making components to represent the application structure

beginning to propagate the app location through the resource system

pushing the Application system one layer higher. along the way, replaced a silly test with a smarter one

abstracted the notion of application path resolution from the resource system

cleaned up the css resource handling of uris that i broke. whoops

okay, the system is stable sourcing its directories from the Application

- multiplexed lookups!
- asset restructuring must continue.  delete the AssetResource and associated

integration testing for the file watch service. now it can be refactored

splitting the watch service into chunks, and isolating the piece of the
JDK that is hard to mock

things are being tested!

shuffling around IO execution to its rightful place

about to start making IO tasks wait upon each other instead of
scribbling all over each other's fine work for naught. the current
solution was working correctly for concurrency purposes, but it's fairly
inefficient now that document requests (and possibly soon others) can
initialize script environments directly.  basically we end up
initializing enough document script environments to fill the IO
executor, and then throwing all but one out

when this was just file resources, i could live with it, but i want
script initialization to be idempotent, and the most correct way is to
synch up in the resource finder when a creation is under contention

some documentation and rearranging, mainly for comprehension

resource creation is now a synchronization point

first one through the gate does the creation job, other threads wait until it is finished and pick up the work

excising the asset resource

fixing a small bug - return undefined when getting a null result back from the client, since null is a sentinel

asset system is gone, replaced with a lookup priority system.
