[r=bac][bug=810113] if multiple ws.op fields are provided, ignore them when generating the page ID

This branch fixes a very simple bug, the page ID mechanism wasn't able to cope with multiple ws.op fields (which are represented as lists instead of strings).

Lint: the lint report is clean

Test: bin/test -c -m canonical.launchpad.webapp.tests -t TestPageIdCorners

QA: load a URL like this: https://api.launchpad.net/1.0/checkbox?ws.op=1&ws.op=2

Looks good save for a couple of typos:

mutliple
alltogether -> altogether

review: Approve (code)

[Brad Crittenden (bac)]

Your review would've been much faster if it weren't for the insane music.
