Updated tester, Mongoman, players, player, and account

@DuaneGarber Take away's:
* Mongoman now accepts middleware and functions. (see account model for examples)
* added mocha test to grunt and remove makefile
  * to test, simply run `grunt test`
  * options include `--stack` to print the stack trace, and `--drop` to drop the DB before running
* `grunt dropdb` will now drop the localhost database tables
* created a tester.js file to help simplify tests (see file for example)
* pushed update, read, and destroy to `players/playerID`
* changed `/players` to be a search keying off query values as search terms 
  *no query params will return the 10 most recent players
