fixed a bug involving text-simulation displaying the wrong timestamp for
each snaphot. Now the first snapshot printed is correctly tagged "-1".
added (for the sake of lazyness) a method to readyqueue letting anyone
delete the first element on the queue. Not having this would imply
rebuilding the whole queue each time a thread was selected to run.

- All the methods accepting a Glib::ustring should
not be exported, instead they should be replaced by wrapper
functions accepting PyObject*.
- The same thing applies to every other method accepting
a ``non built-in'' data type
- Return types should probably be wrapped, too
- It may be a good idea to implement wrapper methods
that print out the content of a C++ object,
so that a Python user can do a simple "print schedStat".
This is achieved by adding a "__str__()" method to the
class. See the SWIG manual for further infos about
returning const char* values.
