Also added an AUTHORS file on the off chance of outside contributions
- 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
- Also made all SQLite tests skippable if the extension is not loaded
- Fixed format of ETags in test server
- Passed any CLI arguments to PHPUnit in the test runner
- 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
