moyhu: More maintained data vizualization pages

Most of the data vizualization pages that you see on the right now have a scheme for automatic updating. I have added this capability to two of them:

	Monthly GHCN plots, with WebGL and shading. These will be updated approx weekly.
	Temperature trend viewer, also updated weekly.

These pages are updated daily

	Latest Ice and Temperature.
	Collection of High Resolution NOAA SST with WebGL.
	Regional Hi-Res SST movies..
