Adding dummy folder marker to project file

This is so that it is possible to tell is you have Bio-formats
or OME copy of this project open through the Oxygen UI. I can be
removed if wished once Specification has gone from the OME repo,
Update (C) year and remove old style sheet
Update namespaces for predicted June 2013 release
Adding 2013 upgrade/downgrade transforms
Fixing the build for specification

With a lot of help from Melissa/Roger/Josh the build now runs
Note, tests do not compile correctly yet.
Correcting classpath and includes
Adding Integration filed, see #8599
Adding Zoom to detector settings, see #8600
Adding SignificantBits to Pixels, see #8531 #7309
Clarify docs for SamplesPerPixel, see #8160
Adding RightsHolder and RightsHeld, see #3753

The downgrade strips the xml blocks but maintains the content as comments.
Convert NominalMagnification into Float, see #9473

This is to allow objectives to be non-integer values, e.g x0.5
The downgrade strips non-integer values.
Merge branch 'develop' of git://github.com/openmicroscopy/bioformats into spec2013
Adding Tuneable (with e) Filter Type, see #7355

This change may be revised at a later point to spell it Tunable (without 1st e).

This change allows a spectral detector to be modelled as a detector with a tunable
emission filter as the last item in the light path.
Adding Annotator to Annotation, see #3736

Added Annotator-ExperimenterID keyRef.
Also adding key and keyref for Annotation IDs.
Adding Transform to Image, see #3742

This also involved moving the AffineTransform complex type
from ROI namespace to OME namespace.
Adding Interleaved to Pixels, see #7309
Adding BigEndian to Pixels, see #7309
Merge branch 'develop' of git://github.com/openmicroscopy/bioformats into spec2013
Updating transform file to include 2013-06

NOTE: 2012-06 still marked as current
