Users can write and save their own special outlines

[frederickobrien]

Suggested by David Pegg, it would be handy if users could have their own personal library of outlines to look up. While talking about it I realised a couple of special outlines in the dictionary ('football' and 'church') were not part of the 'official' list.

A change like this would be part of a far larger project involving user accounts and settings. There are other areas where this could be useful (animation speed preferences, syllabus progress, etc.) though it's a commitment worth weighing up.

Scope also to use phone touchscreens to input outlines? (Related to #6)
