Moved javadoc to src/main/javadoc

Updated all package-info.java files to be located in src/main/javadoc
per Maven best practices.
Use the latest version of pom-scijava
Remove unnecessary version overrides
Update ciManagement URL
Remove obsolete reporting sections
Update organization to more general URL

OME is a major partner in SCIFIO development and holds copyright, but
SCIFIO has its own toplevel URL now to avoid the impression that SCIFIO
is a microscopy-specific project.
Update issueManagement URL
Remove unnecessary relativePath entries

The default value is already ".." so no need to specify.
Use plain English for SCIFIO Tutorials name
Standardize url and inceptionYear

It is fine for them all to inherit from the parent. The inceptionYear
will always be 2011 then, of course, but we don't really need to
distinguish that it took us 2 years to start writing tutorials. ;-)
Add rootdir constant to tutorials

This is needed for the license-maven-plugin to do its thing; otherwise
the license resolver can't find the license folder.
Update license-maven-plugin configuration

The license is BSD-2, not GPLv2. And we no longer need to specify the
roots, since they are inferred by convention.
Standardize licenses block

All components in this repository are BSD-2 now.
Split out jai-imageio version to a property
Remove unnecessary build configuration

All of this is either inherited from the parent, or is already the Maven
default. Isn't it nice to be using the conventions now? :-)
Remove unnecessary plugins configuration

All of this is either not part of core SCIFIO (e.g., the cppwrap
configuration), or inherited from the parent now.
Update mailingLists configuration

We now use the SciJava mailing list for SCIFIO discussion. We will
eventually create a dedicated SCIFIO mailing list.
Update scm section
Update developers blocks

It is easiest to declare the developers in the toplevel POM, and inherit
in all other POMs. If we really need to differentiate who has developed
a specific subcomponent, it probably belongs in a separate Git
repository anyway.
WIP: Remove unnecessary Bio-Formats-specific deps

These dependencies are no longer necessary for core SCIFIO.
