  -----------
  doc: Use gs as alias for grass.script in doc (#282)

Both grass and gscript aliases (import grass.script as ...) were replaced by gs
which is shorter but actually refering to grass.script.

Changes documentation (.html and .rst), examples (files, wxGUI/pyedit),
and how grass.script is accessible in GUI Python shell (wxGUI/pyshell).
Does not change any of the 'live' source code which uses mixture of
import grass.script as grass
and
import grass.script as gscript

Also touches on couple places to clarify references to grass.script
and to GRASS GIS in general.
