Fix for: MFP 2 requests/shows wrong TMS tiles.

https://github.com/mapfish/mapfish-print/issues/68

Several changes in a single commit:

1. Fix for MFP 2 requests/shows wrong TMS tiles.  It was a problem with TileCacheLayerInfo.getNearestResolution which would in certain cases choose the wrong resolution.  This was caused by rounding errors rounding the value down below the needed value.
2. Fix logging in standalone application so the verbose parameter works again
3.  Update all tests to junit 4.11
4.  Add parameter to config.yaml to control the default origin for TMS.
