Prepopulate reasonable default value

[probonopd]

Hi @ximion thanks for making this useful web app.

Maybe you'd like to prepopulate reasonable default values, like I had done in http://output.jsbin.com/qoqukof - seeing reasonable default values always helps me to know what I am supposed to enter without thinking much.

I'm a bit wary of that, as that would create a valid form with the user not filling out all data.
For some values, like the metadata license, we could pick a default though.
At the moment, I am going with help texts as the placeholder property of input elements (but Bulma renders those quite faintly, so maybe I'll simply increase their visibility a bit).

All fields have a default value or helptext as placeholder now, and some even generate default values based on user input.
