Start documentation for free trial creation API
use marketplace instead of community
Started the API for creating marketplaces
Now API call creates a marketplace and admin, but many #TODOs left
Routes and minor fixes
Create category and transaction type when creating trial marketplace
Store the country of the marketplace
Add method for asking email availability
Add Access-Control-Allow-Origin header for int-api
make services use ids as params instead of model objects
Small cleanups and additional tests
Fix documentation location and content [skip ci]
Add marketplace url to returned JSON
remove debug print
fix locale and country up/downcase handling
fix tests
add catch as "dashboard_subdomain" by default

We only need this in Heroku hosting, but there array variables
are hard to set, so instead of changing this to non-array and adding
backwards compatibilty, just add catch here by default
Add confirmation email sending and test for it
Redirect admin to getting started page after email confirmation
Small refactoring based on review suggestions
