This is a major replumbing job of the calculate stats routines. Basically before we used band names to reference any band, but there is a pro

blem with this in that I have discovered that multiband imagery can have more than one band of the same name. Consequently I am reworking eve
rything to reference bands by there number. THere are also numerous other bugfixes here. This commit has been tested to work with single band
 grayscale imagery and paletted images, but not with multiband images (there is still some work to do on this). Also the properties dialog cu
 rrently scans stats for each band - this inefficient, I know about this and will submit a fix for this over the next day or two. I expect the
  multiband support to be commintted in the next couple of days too. Lastly, this patch includes a merge of any other commits not made by myse
  lf over the previous few days.
