Rethink how the options are being passed between dialogs

[jcocchi]

Right now the options are getting passed to every dialog and stored as a global variable to store the conversation state and parameter changes. There is probably a better way to store state- consider using convo/ dialog data.

[jcocchi]

Pass in the options when the dialog is called as opposed to during creation and save the state in privateConversationData instead of passing around the options object
