HackStudio: Make wrapping modes consistent

We were only setting the wrapping mode when triggering the action. So:
- Any editors open without triggering a wrapping-mode action would have
  the default (WrapAtWords) instead of the selected item (NoWrap).
- Any editors opened after triggering an action would have the default
  too.

This fixes both situations, by:
- Storing the current wrapping mode in `m_wrapping_mode`. Later this
  could be loaded from the config.
- Changing that value any time a wrapping-mode action is triggered.
- Setting the wrapping mode on newly-created editors.
