* Slide notes are now linked to the slide XHTML in the PPT output
(TIKA-1840).

(Github-73).
* Fix bug in GeoTopicParser where NER is reused instead of instantiated

* Upgrade rome to 1.5.1 && Downgrade Rome dependency to 0.9 to avoid
nasty NPE (TIKA-1820, TIKA-1516)
* The NamedEntityParser was enhanced to generate text content

* A significant speed-up is made to the GeoTopicParser by
using the new REST server capabilities from Lucene Geo
Gazetteer (TIKA-1803).
* A parser to compute motion properties in Videos, e.g.,
Histogram of Oriented Gradients and Histogram of Optical Flows
using the Pooled Time Series algorithm, was added (TIKA-1798).
* Provide NamedEntityParser which exposes Named Entity Recognition
from OpenNLP and Stanford NER providers (TIKA-1787, GitHub-61,
GitHub-62).
* Allow XHTMLContentHandler to pass attributes of html element
