Refactor the creation and rename dialog

[mathbagu]

Almost all the creation and rename are the same but the code is duplicated.
I propose to create a generic class that can be extended to be completed for all dialogs that uses a NameTextField component:

• Creation of contingencies, folder, action script, configuration,...)
• Renaming

For more complex dialog (virtual case, security analysis), this class should be easy to complete with additional components.
