Title: Remove need for PIL from Helioviewer client

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.
