No testing has been performed yet, but changes are extensive enough to
warrant a commit. Of particular note:
- SQL states are enumerated in a separate trait to reduce duplication
- PDOStatement is now an abstract class to avoid duplication of
engine-specific error handling
- Error handling has been cleaned up somewhat

Also added an AUTHORS file on the off chance of outside contributions
Queries for multiple specific articles are limited in size because of limits on the number of bound query parameters.
Currently this limit is somewhat arbitrarily set at 50, but it may increase.
Historically controllers would be responsible for chunking input, but this will present problems when the expected output is a result set, and of course the maintenance burden increases as the number of controllers increases.
This commit transfers the burden to the data model, and consequently introduces a ResultAggregate class which collects chunked result sets (currently only for articleList).
In the course of making these changes the mock Result class was also largely rewritten, fixing many bugs with it.
This commit does not modify the controllers nor their tests; this will be done in a subsequent commit.
- Result sets are now single-use; this is required for PDO drivers (PDO result sets are not rewindable)
- Change savepoint exceptions to be simple database exceptions; codes remain the same
- Result->lastId() added as MySQL and PostgreSQL have equivalent functionality
- Adjusted tests accordingly
- Cleaned up Database class to make use of this and getAll()
- Fixes#45
- Renamed getSingle to getValue to avoid possible confusion
- Added test to ensure getValue() always returns the first datum of each row rather than going column-to-column
