I think this is working right now. I tried:
`yo angular --jade`
and then
`yo angular:view miview`
which created a jade file:
`   create app/views/miview.jade`
and
`yo angular:view miview2 --jade=false`
with created an html file:
`   create app/views/miview2.html`

Anyway, I'm going to add a description for the Jade option, so it is correctly displayed when typing `yo angular -help`
