[Opensim-dev] Welcome, Avatar!

[Ai Austin]

In a recent commit by Justin he suggested that if a change was made 
to the default viewer welcome message, it would be useful to get the 
thoughts of others first. I do appreciate that most folks will alter 
the string anyway, but it is useful out of the box to have useful 
messages. And I had suggested a change to help differentiate things a 
bit in an immediately visible form at the user end, and to brand the 
system in the default.  Can I suggest this change and see what others think?

Opensim.ini.example         "Welcome to OpenSim"
Robust.ini.example            "Welcome to OpenSim Grid"
Robust.HG.ini.example       "Welcome to OpenSim Hypergrid"

This would have the nice effect of differentiating which 
[Architecture] is being used immediately.
