Fixed connection reference in toplevel pom

The connection entry in the scm configuration was missing a "git:" which
was causing the developerConnection git@github reference not to be
found.

This path should now be correct.
Updated autogen maven dependencies

Removed bio-formats, added scifio.
Updated ome-editor maven dependencies

Removed bio-formats, added scifio
Updated loci-plugins maven dependencies

Added Scifio
Updated ome-io maven dependencies

Added OME-XML
Updated scifio maven dependencies

Removed retrotranslator
Updated test-suite maven dependencies

Added scifio and ome-xml
Remove extraneous SLF4J JAR dependencies

These dependencies are already inherited transitively from scifio, so
specifying them again downstream is redundant. In this way, if we ever
change the logging mechanism for scifio (though we currently have no
plans to do so), no changes will be required by downstream projects.

Utils targets now include base component classpath

Instead of just adding the component's jar to the classpath, utils
targets now also inherit the component's base classpath.
Ant compile targets now depend on jars

Previously, all ant compile targets would depend on the compile target
for their dependencies. This effectively did nothing, and meant that you
could not build targets with dependencies from a clean working directory
(the jars had to already exist, making dependencies irrelevant).

Compile targets now depend on the jar-targets of their dependencies, to
ensure the necessary libraries are built before compilation.
Updated ant autogen dependencies

Replaced bio-formats with scifio dependency in all appropriate targets.

Updated the autogen build.properties so that scifio, instead of
bio-formats, is on its classpath.
Updated bio-formats ant dependencies

Removed JAI and LWF-Stubs from all build target dependencies, and from
the build.properties classpath.
Updated loci-plugins ant dependencies

Added ome-xml and scifio as explicit dependencies in the ant build
targets.

Added scifio.jar to the classpath in build.properties.
Updated metakit ant target dependencies

Added loci-common as a dependency for all appropriate ant targets.
Updated ome-editor ant dependencies

The ant targets for ome-editor now properly depend on scifio instead of
bio-formats.
Updated ome-io ant dependencies

Added ome-xml as an explicit dependency of the ant ome-io targets, and
ensured ome-xml.jar is on the ome-io classpath.
Updated scifio ant dependencies

Removed unnecessary dependencies from all ant targets, and from the
classpath specifications in build.properties
Updated test-suite ant dependencies

Added ome-xml and scifio as an explicit dependency for all test-suite
ant targets, and ensured that these jars are in this component's
classpath via build.properties.
Updated ant to incorporate external findbugs

The ant findbugs targets always required an external findbugs.jar, so
there is no reason to maintain a local findbugs-ant.jar - as
findbugs-ant.jar is intended to be used with a paired version of the
findbugs.jar, and thus the two are packaged together.

Instead, the findbugs task is conditionally defined when the
findbugs.home property has been set.
