Colour interpretation missing in the TMS mini-driver

Description
As detailed in a message to gdal-dev the TMS mini-driver is not setting ColorInterp values on the raster bands it returns. The WMS format doc states that:
BandCount = Number of bands/channels, 1 for grayscale data, 3 for RGB. (optional, defaults to 3)
This suggests that the returned data should be properly interpreted as RGB (and in the case of 4 bands RGBA). This would enable applications using gdal and relying on the ColorInterp values of bands to fully benefit from the TMS data sources (e.g. Mapnik).

default color interpretation is:
1 band: gray,
2 bands: gray, alpha,
3 bands: red, green, blue,
4 bands: red, green, blue, alpha,
5 or more bands: undefined.
Possibly Chris or Adam would like to follow up on this.
