Added initial incomplete implementation of the Leica TIFF series composite reader.
Added initial support to the Leica TIFF series in MicroscopyProcessor.
Replaced loci_tools.jar with bioformats_package.jar and reduced debugging info in MicroscopyReader.

Still investigating with LOCI why there are all those apparent exceptions logged even though there does not seem to be real issues with the code.
Updated dss client libs to version S188.
Composite datasets can now also be edited in the Microscopy Editor.
Store the type of the composite reader in the attributes.
Merge remote-tracking branch 'aarpon.ath.cx/feature/composite_datasets' into devel
