It seems that Chrome orders fields of objects in order of array key.
Therefore we must stop using user.id in the PHP arrays, and instead
ensure that we use sequential numbers.
This commit fixes the user selector.
The problem is to do when you pause a bit, so a search starts, and then
type a bit more before the search finishes. It was behaving like this:
1. Type a bit, then pause.
2. First search request sent.
3. Type a bit more, then pause.
4. Second search request sent.
5. First search request completes.
6. You try to select one result.
7. Second search request comples, overwriting what you are selecting.
This fix works by cancelling the first request before sending the
second.
* YUI3 used instead of YUI2, converted all YUI2 components to YUI3 equivalents.
* Renamed user/selector/script.js to module.js
* Converted uses of the the user selector to YUI3 + the new events
