Since we're targetting the latest LTS release of Ubuntu as a nice
baseline, and that currently only supports 1.46, we need to remove the
nice steady_timer code. For now.
This commit should probably be reverted once a newer version of Ubuntu
LTS is available.
* server/IdleConnector.cpp, server/IdleConnector.h: A generic sigc++
based class for functions which need to be called regularly.
* server/StorageManager.cpp, server/StorageManager.h: Add a method
to be called once a second from the idler.
* server/server.cpp: Hook the idler up to storage manager.
