plus a few code structure / component changes:

• separate out components from main export-modal.jsx. Primarily a new ace editor component and select-box component
• create copy successful messaging
• make sure copy always works
• level out and vertically align titles / buttons for ace editor. Currently export-to and select box are misaligned
• write a few more test cases for each component and modules – going to make another ticket for this!
