Can't remove users from organizations

[ross]

When you remove someone, without adding them, the text box at the bottom (which should probably autocomplete) is empty, and this causes problems on the server.

Ideally when you add a user (select from the autocomplete) it would add another row to the table, defaulting the user to editor and setting the names to user{{X}}name and user{{X}}capacity where X is $('tr').size()
