WIP: Assign question to story

Questions search form works.

Assign button doesn't :P
POST /story/:id/questions/ { _id } to assign
POST /question/:id/answers to draft new answer
FIX: Editor can assign question to a story
POST /question/:id/answers/:id/journal/:id/apply

Also single answer view and answer draft view.
Populate author in Question.findAnswers
Show author's name as title and text as subtitle
POST /ansers/:id to store new draft of an answer
Show alert if user have drafted answers
FIX: Can't publish answer
FIX: Score is undefined in search results

There was a typo :P
Global search initial implementation

Takes questions and stories into account.

Stories score (calculated by Elastic Search) is divided by 10
and added to each abstracted question's score.

Seems fine.
Dockerfile to build images from
Use config objects mongo settings to config river

Search plugin now reads global configuration to setup mongo river.
Merge branch 'search'
Orchard fig readiness

fig.yml to setup all services.
FIX: use url.hostname instead of .host for river

url.host contains port as well as hostname. This breaks things.
Merge branch 'search'
Translations imported from legacy R20 project
Additional strings translated

also few text-related fixes.
