[WIP] First PR

Hello @pelletier @danielbreves @jwswj @svizzari @atroche @tmcinerney

I built this App in the plane yesterday

It's still super bare bone and I'd like to go a bit further, could you guys give me a few pointers (using examples in previous apps if possible?) on how to (I couldn't find that by myself in an understandable way)

- hide/show a button based on the dropdown value (or better yet changing the links for each buttons based on the value of the drodpown?) which one is best?

- define a variable from what is being entered in a text field inside the App. I can't use this.ticketfield anymore because in the case of my "newshipment.hdbs" the value entered here isn't in a ticket field...

Thanks!

:airplane: 

PS: I learned a few things that might be interesting for our demo apps:

1) When a noob builds a new App he really doesn't want to care about translations.in fact they broke my app quite a few times since I copied/pasted from other apps... @jwswj how could we satisfy zendesk i18n standards and at the same time making it painless for new developers to learn?

2) our sample Apps (maybe because they aren't over yet) don't have enough examples or URL manipulation and variables in URLs

3) our sample Apps code don't have enough comments... I stumbled upon the magento App written by Jason and the comments every couple lines helped immensely (examples [here](https://github.com/zendesk/magento_app/blob/master/app.js#L77) and [here](https://github.com/zendesk/magento_app/blob/master/app.js#L88)
