GEOMESA-337 - Speed up writeFeature

* Refactored the Formatters to take the information they might use.
* Additionally, Formatters produce Text at the last moment.
* Simplified a CRS lookup to assume 4326.
GEOMESA-318 Export to STDOUT not working for GML, GeoJSON

* Fixed issue with correct output stream not being assigned when exporting.
* turning collectStats off
* changing logger statements
GEOMESA-160 DWithin for non-point geometries

* Removes assumption that DWithin geometry is a Point.
* Adds tests to show that the filter is working as we expect the rewrite to.

Randy Attai submitted the original fix.  I cooked up the uni tests.
GEOMESA-327 fixing Try around hadoop initialization
GEOMESA-132 Create a branch that is compatible with Accumulo 1.5 and Hadoop 2.0 (instead of 2.2)

In addition to down-grading the version of Hadoop, this commit
also uses gt-epsg-wkt in lieu of gt-epsg-hsql, and relies on
Scala 2.10.3.

NB:  To test, this build was installed on a VM that used
Hadoop 2.0.x and Accumulo 1.5.x.  The quick-start tutorial
worked as expected, including visualization through
GeoServer.
GEOMESA-300 change artifact names in hadoop 2.0 branch
