Migrate loci.common to ome.scifio component

Classes have been migrated to ome.scifio.common, ome.scifio.io and
ome.scifio.xml packages.

Unit tests have been similarly migrated based on function.

Build files for both Ant and Maven have been updated accordingly.

Removed loci-common.jar from loci tools deps

As the loci-common jar was absorbed into SCIFIO, it has been removed
from the loci tools dependency list in the ant toplevel.properties file.
Removed ant references to common targets

Removed all references to compile/jar/clean/etc... common from ant
targets.

These targets now depend on scifio if they did not already, as the
common classes migrated there.
Updated ome-notes dependencies to jar-xxxx

Updated the ome-notes dependencies to point to jar- targets instead of
compile- targets.
Removed loci-common from Maven references

Updated all poms with a dependency on loci-common. If a project that
depended on loci-common did not previously depend on scifio, a scifio
dependency was added.
Updated build.properties to remove loci-common.jar

As loci-common was migrated into SCIFIO, there is no more loci-common
jar. If a project that depended on loci-common did not previously have a
scifio dependency, that project now depends on scifio.jar.

Updated showinf dependency on loci-common

Removed the loci-common include in showinf.cpp and updated package
reference from loci.common to ome.scifio.
Removed loci-common ref in LibraryChecker

LibraryChecker now looks for RandomAccessInputStream in the
ome.scifio.io package of the scifio.jar instead of loci-common.
Removed loci-common ref from ome-tools

The assembly.xml in ome-tools referenced the loci-common jar. This has
been removed.
Initial copy of loci.common to BF-Legacy

This is the first of 2 commits to preserve backwards compatibility with
the legacy loci.common package.

Bio-formats-legacy is not in a functional state with this commit. It is
simply a copy, with no changes, of all loci.common classes from the
scifio component to the bio-formats-legacy component. This will ensure
that the delegator classes will have the same history as the original
classes.
Added bio-formats-legacy component

This is the second in 2 commits to preserve backwards compatibility
within the loci.common packages.

all loci.common classes within the bio-formats-legacy component have
been converted to delegator classes, which pass functionality to the
maintained ome.scifio equivalents.

This change ialso includes maven and ant targets, making
bio-formats-legacy fully functional.

Added bflegacy dependency to ome-notes

The ant and maven build systems for the ome-notes component have been
updated to include a dependency on the bio-formats-legacy component.
Added bflegacy ant target to tools bundle

The bio-formats-legacy jar will now be built as part of the ant tools
target.
Updated utils imports to ome.scifio.common

Utility classes in the scifio and test-suite componenets were still
referencing the deprecated loci.common package.

For projects in development such as these, the imports are updated to
ome.scifio.common (as opposed to using the delegators in the
bio-formats-legacy component)
Removed common component directory

With the bio-formats-legacy component fully functional and all
loci.common classes in development migrated to ome.scifio packages,
there is no need for the common component.
