[GRASS5] NVIZ startup

[Bob Covill]

Hello,

I have applied a change to the NVIZ startup script for more flexible
handling of parameters. The -h and -help flags are still handled by TCL,
but all aother arguments are now passed to NVWISH. 

This way the arguments are handled by the G_parser allowing more
flexible entry.

eg. nviz2.2 e=test.dem ve=contours site=data2
