  r.null.all: add wrapper around r.null for multiple maps (#52)

r.null.all uses g.list wrapper to select all raster maps or a subset.
g.list syntax options are supported but are driven by an option,
not flags with an explicit default value for selecting all maps.

r.null flags are supported as flags, but the dry run mode of r.null.all
does not take these into account.

Includes suggestions from code review by @neteler:
Use plural when we have multiple examples. Use plain Bash/CLI syntax
and full option names in examples. Add missing comma in a see also list.
