r3.colors list map name under "optional"

[marisn]

The most important options for a r3.colors module - a map name and file with map names (why such option exists?) - are listed under "optional" tab. "Remove" and "Print" could go to "Optional" but not the most important parameter - a map to operate on.

Hopefully fixed in r53782.

The file option was added by me to support the color table creation of a large amount of maps. The file option comes handy in case the the maximum shell command buffer size is reached and xargs is no option, or in case the maximum Python command argument buffer size is reached. In addition the output of g.mlist can be piped into a file that can be used as input file for r(3).colors.

The file option is used by t.rast.colors to compute and set the color table for a space time raster dataset.
