added some client-server tests to check for userId
allow noHookXXX for both client and server
renamed noHook to direct to keep terminology consistent
make this.userId available to before/after find/findOne within server publish
remove directPublish var from wrong spot
move directInsert/update/remove back to server-only to mitigate undesired behavior of having validated versions still being called
trash this.userId in favor of passing userId as first argument for find/findOne before/after hooks
add explicit underscore dependency in preparation for next meteor release
added find example in readme
