[GRASS5] Messages and GUI

[Huidae Cho]

What about having a global message index so that we can number all messages:

GRASS_INFO_ERROR1
module message 1
GRASS_INFO_ERROR2
driver message 1
module message 2
module message 3
GRASS_INFO_WARNING3
module message 2
GRASS_INFO_END3
...
GRASS_INFO_END1

But, I think a prefix will work better and easier.
