Updated Components document, comments on Implementation Cycle

I think the bullet list order could be different, to follow the cycle 
concept:

1 (was 2). When ... content ... developers and users.
2 (was 1).  When user agents ... developers.
3 (was 4). When developers ... authoring tool.
4 (was 3). When authoring tools ... content.

And perhaps add another item at the end:

5. When content (start around from #1)
