Test for 3.x.
Update doc/source/guide/helioviewer.rst

Updated to make a note of the need to install OpenJPEG.
Update doc/source/guide/helioviewer.rst
Previously, the helioviewer client required PIL to be installed since OpenJPEG did not write PNG files, and matplotlib only read PNG natively (requiring an intermediate format).  OpenJPEG v2.0 now writes PNG, so PIL is no longer required for Helioviewer client.  Further, the hv client returned upside out images when reading a local jp2 file; this has been fixed too.
