* Fixed issue with "db" variable having to be in the store
* Tested getDbQuery with extrapolation/preparation of docs in parallel
* Created function _extrapolateAndPrepareAll for Store.js to make getDbQuery as short as possible
* Added sendErrorOnErr to getDbQuery to shorten it further
* Fixed silly bug where ObjectId was reset on updates with put
* Turned after*** functions into async ones, as they will likely to more DB operations etc. These are now called BEFORE sending data to the clien
t, and AFTER adding records to the database
* Fixed silly errors in SimpleSchema, where p. was missing in some places
* Added options to echo information back to client if they want
* Added idProperty to the MongoStore class
* Added a paranoid check in case (nearly impossible) somebody submits /id and then o._id is different (the URL wins)
* Updated documentation
* Other small improvements
