[kepler-dev] "Look Inside" changed to "Open Actor"

[Christopher Brooks]

The Kepler group asked that "Look Inside" be changed to "Open Actor".
[Personally, I was opting for "Open Sesame" ]

http://bugzilla.ecoinformatics.org/show_bug.cgi?id=2110

I went ahead and made this change to
  ptolemy/vergil/actor/ActorController.java
I also modified the short cut so that Control-O now opens the
actor instead of Control-L.  If there is great hue and cry, I suppose
we could have both Control-O and Control-L but I don't see how to do
this.

ActorController has a protected variable named _lookInsideAction which
I did not rename so as to preserve backward compatibility with
subclasses of this class.

I updated a few demos as well.

These classes:
  ptolemy/chic/ChicController.java
  ptolemy/vergil/fsm/TransitionController.java
  ptolemy/vergil/fsm/StateController.java
all still have "Look Inside" because the "Look Inside" action looks
inside a Chic node or a transition or a state, which are all not
actors.  Thus "Open Actor" does not make much sense in for those
classes.  If someone has a strong opinion, I could change them as
well.

Once the dust settles, I'll make a pass through the docs and fix up
references to "Look Inside".
