Changed default locale to :en
Added a REST API for creating and updating companies. The API can be called e.g. with curl

Create new company:

curl -H "Accept: application/json" -H "Content-type: application/json" -X POST -d '{"name":"My Great New Company","company_type_id":2}' http://localhost:3000/api/1/companies

Update existing company:

curl -H "Accept: application/json" -H "Content-type: application/json" -X PUT -d '{"company":{"name":"My Great Updated Company"}}' http://localhost:3000/api/1/companies/1002
