Fixed many errors in queries:
- Prepared statement wasn't running at all :)
- Returning feed ID rather than subscription ID
- latestEdition wasn't matching
- Fixes #55
- Included test for Context
- Adjusted Database::editionLatest() to use Context
- Adjusted NCN handler and tests accordingly
- Also refined experimental Database::articleList() method and added experimental Database::articlePropertiesSet() method
- Makes use of PHP's internal Web server to deliver expected responses from a real server
- Windows batch file can be used to run tests (Linux and Mac test runners to come later)
- Added PHPUnit to dev dependencies
- Test files now consist entirely of traits:
- General setup trait mocking User class and cleaning up
- Driver trait to set up the database connection
- Series trait containing tests for the series, independent of driver used
- RuntimeData has now been replaced by a single static Data class
- The Data class has a load() method which fills the same role as the constructor of RuntimeData
- The static Lang class is now an instantiable class and is a member of Data
- All tests have been adjusted and pass
- The Exception tests no longer require convoluted workarounds: a simple mock for Data::$l suffices; Lang tests also use a mock to prevent loops now instead of using a workaround
