  wxGUI: Ask user about shell only when present (#1219)

Introduces two new functions to check for shell presence and PID.
The environment is accessed twice now, to construct the dialog and to end the shell.

Default button is now Quit.

Shell/terminal/prompt is not just called shell because that's really what is being ended.

Updates outdated doc to new behavior. The doc described some previous state, not the current state before this change.

The section is restructured and changed to be about GUI and CLI rather than starting
otherwise it is confusing for a reader studying GUI as a primary or first-contact interface
of GRASS GIS.
