[Etoys] scriptor menu and bigger color picker for painting

Hello,

I published two more changesets to OLPC update stream. One is about the menu of Scriptor. If you go to textual editing and come back, it now rightly ask confirmation. Another (from Abe-san) is about making the color palette of painter bigger.

In regards to the menu, there are a lot of places where the ordering of items in a menu is arbitrary. We should make up some guideline on the ordering, such as:

* The impotant ones come first, and less important ones come later. * The destructive ones come later.

and look at these menus.
