New modes for gdaldem

Description

I have added three new outputs by cloning the slope code and changing the formulas. I have implemented three simple derived terrain measures, which are useful to habitat suitability modelling. These measures are TRI - Terrain Ruggedness Index, TPI - Topographic Position Index, and Roughness as defined in Wilson et al (2007) (​http://www2.unil.ch/biomapper/Download/Wilson-MarGeo-2007.pdf)

I include the code for gdaldem.cpp and the utilities documentation gdal_utilities.dox

Thanks for the patch. Applied in r17577 /trunk/gdal/apps/ (gdal_utilities.dox gdaldem.cpp): gdaldem: add 3 new mode : TRI, TPI, roughness. Patch contributed by Chriss Yesson (#3109) and restructured to factor general 3x3 processing for much better readability&maintainability
