Fix javadoc warning.
Notes
JENA-813 : Add javadoc to note when IteratorConcat is better.

Prefer IteratroCons in Iter.append and note not good style for large
numbers of iterators.  Consolidate other changes.
Add Class<?> log selector variants.
Remove warning about a situation that can now happen.
For reference : the cfg file for default settings.
Tidy comments.
Correct javadoc
Make resolveStringSilent silent.
JENA-811 : Make RDF/XML resolve the base IRI silently.

Non-parsable IRI strings are still an exception but parsable strings
which trigger any higher level checking will not cause a parse to abort.
Use a small footprint setup for the system database.
Merge branch 'master' of https://git-wip-us.apache.org/repos/asf/jena
Correct comment
Update jsonld-java from 0.5.0 to 0.5.1
Don't RAT files that are JSON (no comments)
JENA-808 : correct order of assertIsomorphic arguments.
Reformat comments.
Typo
Jena-1/2 mention - now rather old.
Remove unused.
