Invert VIIRS images

This release allows to invert the raw VIIRS images per Band.

Concurrent processing changed for VIIRS files

I changed the processing of the VIIRS files to a sequential process because of the difficulties in an multi-threading environment of the HDF5 libraries.

FengYun 2E and FengYun 2G added

Two new tabs will show the FengYun 2E/2G files from 'Data Channel 12'.

SOIL lib removed

Using stb_image ( v2.06 - public domain image loader - http://nothings.org/stb_image.h) avoids using the SOIL library. It is possible to compile the source in Qt 5.5 (in Windows and Linux) . The Windows zip file contains all the necessary DLL's for running the program.

Initial release

The release for Linux requires the Qt5.5 shared objects while the Windows version requires the Qt5.4 DLL's.
