psychon bf6dc459db WebModules: Fix a crash during shutdown ...

During shutdown, the global list of sessions is destroyed. The new multimap
which counts sessions per address is also destroyed. However, they are destroyed
in unspecified order. This is not what we want because destructing the session
map also destroyed all the sessions which then has to access the sessions-per-ip
multimap. This obviously crashes if the multimap was already destroyed.

The fix here is to introduce a new class that contains both of those maps and
makes sure all the sessions are destroyed before the maps are destroyed
themselves. I hope this description makes some sense...
