elvez 09ad981251 - Make the schedulables widget do something useful, now that I know it was the simulation widget, not the schedulables one which completely put KO my system...

tchernobog 0b4db098eb - Add History::clear() to empty an existing history (equivalent
to removing all of its resources and all of its processes, but
faster)

matrevis cfd7a025db - Added a best-effort preferences dialog:
the user may now add plugin directories,
  policy directories, and set the simulation
  speed.
- Added some menu voice to the main window.

tchernobog 45ef305a1b - Incapsulate code so that the hack we previously used in CPUPoliciesGatekeeper isn't needed anymore
- Now CPUPolicy has a callback method for scripting languages, but it is up to derived classes to take
mutexes and set the value when needed (maybe we can improve this?)

- Better textual output.

elvez 436e401ae8 - Added a tree widget as a temporary replacement for the cairo-based one. it`s still incomplete, but I should get it working in no time now that I understand how to use it
NOTE: to use it _SG_SCHEDULABLES_TREE_WIDGET must be defined, which is obvioulsy not, by default

elvez 48fc2f5a00 - Added still more error checking to PythonCPUPolicy. But the code which calls its methods should be updated to handle the new exceptions...

matrevis d72ce96508 - Corrected a bug in step forward, which was incorrectly assuming
that the size of the history was the coordinate of the instant
  to add.
- Corrected a bug in step forward, which was incorrectly assuming
  that all processes started at instant 0.
- Added a wizard to show a bug in step forward, which thinks that
  the simulation is terminated while it isn't since some processes
  are still future.
- Commented some unused code in step forward (extendThread()).
- Still to extract methods from Extender and provide them to 
  step forward in a more suitable (static) way.

matrevis 574723a35b - Added full request support, altough still not working
at all. Compiles and runs, but the output is not
  correct. Anyway, now it is just a matter of logics :P
- Corrected some minor bugs in step forward.
- Step forward is now rather messy, but still better than
  four hours ago.. altough this can be hard to believe.
- Added some wizards that help finding bugs.
- Rewritten dyn process get_state as it was guilty of
  premature optimization :)

matrevis efe7dedd61 - Request queues are now correctly managed by the ConcreteEnvironment
copy constructor and by the add_resource and remove_resource methods
  found in ConcreteHistory.
- Scheduler now adds the requests in the queue when appropriate, and
  removes them when exhausted.
- Still to implement the management of the state of requests depending
  on their position in the queue
- Still to implement the way threads block depending on the state of
  their requests
- step_forward now reuses some bunch of code taken from the prototype

set_notify_enabled(false) before starting)

correctly).

matrevis 96055b4cf1 - minor bugfix: scheduler was terminating subrequests before decreasing
their elapsed time
- requests are now behaving nicely, since they are raised at the correct
  instant, and terminated at the right instant
- the ready queues are still not ready, tough :(, anyway, now there is
  really nothing else to do before them.
- stepforward is looking much more uglier (if possible).

matrevis 56a7ce1221 fixed a bug involving scheduler keeping a running thread in the ready queue
when that thread had just been given the cpu.
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.

Small commits avoid complex mergings.
