Locations should be an array

[axos88]

!!! BREAKING CHANGE

Locations and try_files are made into an array.
Configuration files will need to be adjusted.

    locations:
      - name: /
        try_files:
          - $uri
          - $uri/
          - /index.html
      - name: /images/
        try_files:
          - $uri
          - $uri/
          - /index.html

Hmm... In the end I think not only try_files should be treated separately, but almost any param given to locations - if an array - should be joined using spaces.

What do you think?
