Adapt front-end to be more stateless

[cuducos]

Nowadays passing information (Language basically everywhere, parentId for RelatedTable etc.) has proved too verbose (and adds unnecessary complexity — e.g. with Html.map).

This design is more promising.

I can work on that, just played a bit with the code to remove Language from Inputs, and oh my god, it is so much simpler now, I can see a big refactor coming (:

I believe it will be easier if we merge #130 (to avoid conflicts) and #127 first (I've pulled the branch to try, much easier to work with docker :P)

Great, that'd would be awesome — many thanks for the enthusiasm!

Just a bit of context around the PRs:

• I hope Using docker cache with build of elm and add target to sample data #127 is merged today: there was a bug in it, but hopefully I could fixed it — as soon as @gomex review it I can merge I guess
• Elm refactor: performance and readability #130 will be merged later today by @jtemporal or @anaschwendler I guess

If you wanna pair on this issue, just drop a line ; )

Both done ; )

I'm kind of waiting for progress on #61 so this architecture refactor can be part of the UI/UX refactor proposed there.
