wxgrass: should automatically open display if layer added with no open display

[mlennert]

IMHO, wxgrass should open a display window automatically if none is open and a map layer is added. Currently it gives this fairly cryptic error message:

Traceback (most recent call last):

File "/home/mlennert/SRC/GRASS/grass_trunk/dist.i486-pc-

linux-gnu/etc/wxpython/wxgui.py", line 1145, in AddRaster?

Should be fixed now in trunk, r30833. Martin
