Change job classes to be instantiated rather than calling methods statically. This obviously makes it easier for state information to be destroyed after a job runs. This change is NOT backwards compatible and requests job classes be rewritten. Jobs also no longer receive arguments in the perform/setUp/tearDown methods but instead are passed as a $args variable to the instantiated job

 ### Defining Jobs ###
 
 Each job should be in it's own class, and include a `perform` method.

-		public static function perform($args)

+When the job is run, the class will be instantiated and any arguments
+will be set as an array on the instantiated object, and are accessible
+via `$this->args`.

 Any exception thrown by a job will result in the job failing - be
 careful here and make sure you handle the exceptions that shouldn't
 result in a job failing.
 
 Jobs can also have `setUp` and `tearDown` methods. If a `setUp` method
-is defined, it will be called along with `$args` before the `perform`
-method is run. The `tearDown` method if defined, will be called with
-`$args` also, after the job finishes.
