[Opensim-dev] How to lower .net host did not respond error messages.

[R.Gunther]

0.8 release
I think its one for mantis.
But on my console you see since 0.8 to mant connection error messages to
other server that dont respond with as example HG freidns and IM etc.

Means the error dont get handled good and report a small error line.
But meanwhile the console is sometimes red or full of errors.
So how can you disable the error messages on the console ? the can btw 
stay in the log.

need a fix anyway. so its only printing a short error.
