Extra 'Confirmation' click for archive subscriptions is unnecessary

[Michael Nelson]

This bug was factored out of bug 386355.

Currently when someone subscribes me to an archive, I visit:

https://launchpad.net/people/+me/+archivesubscriptions

and then:

1) Click on the 'confirm' link, which opens an overlay (or, with js turned off, displays a new page with a form asking me to confirm the subscription,
2) I then read the information and click on the 'Confirm' button, which activates the subscription for me (creating a personal token),
3) The instructions are then displayed on the screen.

Step 2 above could be removed if we instead use a Confirm button at step (1) (inside an appropriate form).

For consistency with the rest of the changes that will come with bug 386355, the button can be re-labeled "Show Me How".
