Add plotting RGB(A) image stacks
RGB image files are now read with the RGB dtype and can be plotted
Updrade tifffile to version 2013.05.02
Add reading and writing RGB tiff files and improve. In addition the axes names and tags of tiff files are now read where possible
Merge branch 'master' into ENH_plotRGB
Disable colorbar when plotting RGB
BUG-FIX: when writing to tiff the photometric tags was not properly set what was causing problem on loading (reported by P. Burdet)
Add uint <-> RGB conversion to change_dtype
Add RGB tests
Merge branch 'master' into ENH_plotRGB

Conflicts:
