Final FIWARE software release

Main contribution of this release is the Access Control feature:

• Facilitates data reliability.
• Facilitates data confidentiality.

This is accomplished by following sub-features:

• Requires credentials to modify data content.
• Viewing data either free or requiring credentials.
• User management.
• User identification by FIWARE Lab KeyRock or Google account.

Documentation Improvements

This release improves the documentation: GitHub Pages, Apiary documentation, installation script, installation manual, and the README.md.

Quality Boost

This release contains mostly bug fixes. Additionally a couple of interface changes are introduced:

1. In internationalized texts the language key for the language-independent text is changed from "" (empty string) to "__" (two underscores). The reason is that MongoDB does not accept zero length keys. SQL script to update the database: install_scripts/update_fw_core_intl_to_5.1.sql
2. Two resources are added to the interface to facilitate automatic configuring of POI-data editor/validator functionality in clients.

• poi_schema.json - Full JSON schema of POI data supported by the server
• poi_categories.json - Description of POI categories supported by the server

Dynamic POIs

Some of POI data might be fetched from other unrelated servers e.g. web pages.
