- Substitute the old SchedulableQueue with the new ReadyQueue

- Add interfaces for Process and Thread into the "sgpem.i" SWIG
interface file, change DynamicSchedulable into Schedulable
- Add dynamic_cast for the return value of ReadyQueue::get_item_at()
into the pyloader "sgpem.i" SWIG interface, so that a Schedulable
can be either recognized as a Thread or a Process
- TODO: wrap STL exceptions in SWIG interface
- Please note that code won't compile until the new History and
Scheduler::step_forward() will be in place. This is a known issue.
