  d.region.grid: Add new tool to display grids (#635)

d.region.grid is a wrapper around two d.grid calls. Unlike d.grid, d.region.grid can display grid lines
for the a computation region without the user first getting the resolution manually.
It also respects that the resolution might be different in each direction.
Finally, it also supports displaying grid based on a resolution of a raster map.

It has limitations inherited from d.grid, so it can't limit the grid extent (d.grid draws full rendering extent/region)
and it can't draw marks instead of lines (d.grid has one resolution and uses that to draw a point grid).

Two possible lines of uses cases are drawing region grid where the EW and NS resolutions differ
(requires two d.grid calls) and drawing grid of raster or region (no additional calls needed to get the
resolution, unless you are in GUI, but there you can at least avoid handling the numbers directly).
