Moved SCIFIO-tools to scifio

Moved /tools and the scifio-tools component to this repository.
Restored config folder

Moved the config folder, which contains Eclipse style specifications, to
this repository.
Removed ome-xml dependency from ImgSaver

This dependency wasn't being used right now. It's only needed for
calibration values, which weren't being populated anyway. SCIFIO will
probably need to include physical pixel sizes itself eventually.
Removed LurwaveServiceImpl

Moved constants to LurwaveService and removed the Impl because of its
dependency on LWF-stubs. The impl belongs in Bio-Formats.
