add fork of addjars-maven-plugin

the plugin is adding the android-support dependency twice, so adding in prep
to provide a workaroiund.
patched to not install provided dependencies.

the addjars project installed multiple copies of the android support
package, which because it was provided already led to duplicate deps.
