Revert to Editor should open in Edit Mode

[magico13]

When reverting to editor with rollout times disabled, it should load up the editor in "edit" mode for that craft, to make things potentially easier. Additionally, it might be worth it to have the "Save/Cancel Edits" buttons not switch back to the space center, but instead just switch to normal mode and do the appropriate action. Then players can easily switch to work on something else.

Also, while in the editor you should be able to open the build list and edit any vessels that are in storage.
