Internationalization added.

Added i18next module to handle internationalization on both the
client side and server side. Client and server use different
configuration files but share translation files.
Client side implemented for About page only, so far.
Server side hook implemented but not yet tested.
Added jsonlint to grunt file to check longer and more complex
JSON files used for holding translations.
Also folded in most changes for the Fair Trade variation of
the application, primarily to include the About page.

Removed project refs.

Removed additional references to projects from the home page and
about page if the UI configuration is set to not use projects.

Also combined the customizations that used to be separated into
another repo, to simplify maintenance. This was mostly due to
the addition of a home page in the main midas codebase.
