[BUG] Adding a gift option breaks campaign

[BenSturmfels]

I can create a campaign by clicking through and adding a name, description etc. The campaign successfully accepts payments. If I then add a gift option, I see a bunch of JavaScript errors in the console, and the donate button no longer works.

The error in the browser console (development mode):

Uncaught TypeError: vnode.data is undefined
    updateEventListeners eventlisteners.js:22
    createElm snabbdom.js:95

    init gift-option-list.js:28
    init page.js:51
    js page.js:168

eventlisteners.js:22

Perhaps also worth noting that after adding a gift item, the title and description show as blank in the "Manage Gift Options" dialog. May or may not be related.

@wwahammy if you had a chance, would be great if you could take a look at this one. The gift option would be very useful for T-shirts.
