test refactor; metriqued not required to already be started before running tests, tests start/stop metriqued once per test; updated/added tests for jsonconf, metriqued, csv and json cubes (including extract/save); added test fixtures like test ssl cert, json, csv; refactored metriqued.logging to config on tornadohttp.__init__ rather than in config and metriqued.config so it matches current model used in metrique.config (uses defaults rather than properties when possible); new default locations for configs is ~/.metrique/etc/[metriqued.json,mongodb.json, metrique.json]; logs ~/.metrique/logs
