Update Tika buildouts for JAXRS server (ftw.tika 2.x) 

This PR adds a new `tika-jaxrs-server.cfg` to download and configure the new [Tika JAX-RS](http://wiki.apache.org/tika/TikaJAXRS) server, which is required by `ftw.tika` 2.x.

It also updates  `plone-development-tika.cfg` for the new server.

The existing `tika-server.cfg` is still present, and will continue to work with `ftw.tika` 1.x.

@jone updated that issue with some more details to the suspected cause. I can take a stab at that tomorrow. :wrench:
