Switched from jarjar to maven shade plugin

Due to issues around null failures within jarjar plugin on various
machines, switched to maven shade plugin.  Maven shade plugin ended up
provided additional features over jarjar and increased speed of build
(upon all dependencies being downloaded) to just over 2 seconds from 8
seconds with jarjar, from antrun that was over 30 seconds, and the
original ant that was quite long as well.

Updated slf4j & logback licenses to latest noted on websites (generally
just formatting & copyright date)
Added licenses to the jar build which is in addition to the zip build
with configuration layout.
Restored a prior cut of producing source files.
Cleaner non any manifest build
Fixed prior change log pull number for 28
fixed pull version

copy / paste error (again)
Merge pull request #29 from hazendaz/maven
