Code review comment for lp:~cjwatson/click/libclick

I chatted with Thomas about this today. He doesn't think he's going to want major rework, although would like to carry on reviewing. We agreed that I would go ahead and land this anyway (since libclick is blocking other things, and it would be good to try to squeeze it in before Qt 5.2 breaks landing for however many days), and if he finds issues that I need to bump soname for then so be it.

(Let me know if anything here is inaccurate.)
