Context Menu Status

Initial Points

• I'm adding m_show to INTERFACE_NAMES for the english text "Show", this will need translating to the various dialects.
• If Context Menu is shown and a menu item is selected, on Windows at least the keyboard then ceases to function. It works fine if the 'Pick' option is used from the context menu. It may be possible that the context menu leaves the editor in an invalid state.
• The command structure in Studio would benefit from being reorganized in a uniform way so that commands may be retrieved without having intimate knowledge of the data structures in Studio. This could also benefit a plugin mechanism should we go down that route.
• There is no interface for class 'move' refactoring method.
• Selection behavior needs to be consistent in Studio editor. If I select text in the Studio editor, then right click over a class, I expect the selected text to be the 'context', not the class. This requires a change in the pebble retrieval mechanism in the editor when contextual pick and drop mode is activated.
