problem with logstream found

[Tommi M�kitalo]

Hi,

logstream has indeed a problem: ios_base needs to be initialized. Normally 
should happen by calling basic_ios<...>::init(), which is protected. Before 
calling init the values are undefined. Width() returns on my machine 
2507262709. This is not very useful to set up the wostingstream. The 
example-program segfaults.

I think it would be better to derive logstream from ostream or do not derive 
at all. I removed the base-class and the example-program works now. Here is 
my patch.

I fixed also another bug: The stream must be cleared in flush even when 
logging is disabled.
