I made several enhancements to the BOUT reader. These include modifying
the reader to be able to read variables that contain ghost zones, being
more tolerant of data type variations in the files and adding more error 
checks for bad values in the files. This resolves #1984.

I modified build_visit so that manta is not be built unless the --manta 
option is specified. This resolves #1990.

I updated several files for the upcoming 2.8.1 release.

I modified build_visit to add -DVTK_REPORT_OPENGL_ERRORS:BOOL=false to
the VTK build. This corrects a performance issue with VTK 6.1.0 when 
using x forwarding over ssh. I also rebuilt VTK 6.1 on rzmerl and updated
the config site file to use VTK 6.1 instead of VTK 6.0.

mfem updates: tvarying md + sil and multi-domain support

I corrected a bug in the ExecuteDataTree method of avtDataTreeIterator 
that I introduced when I switched it to work with avtDataRepresentation. 
I also corrected a bug in several filters that the fix exposed.

I converted the remaining filters to use avtDataRepresentations instead
of vtkDataSets.

I removed all the remaining traces of vtkDataSet from avtDataTreeIterator
since all the filters have been converted to use avtDataRepresentation.

I finished adding the ability to use EAVL with VisIt and enabled it on
edge. This includes adding the ability to select between VTK and EAVL
in the preferences window in the GUI, modifying the config site files on
edge to build with EAVL support, and making a few more fixes to get EAVL
working in the compute engine. Currently, only the contour filter uses
EAVL.

I modified the script that runs the regression suite on edge to load
the cuda module so that VisIt configures properly.
