* Rebase all current servers on common abstract BaseOpenSimServer class

* The immediate upshot is that "show uptime" from the console will now show uptime on all server types (user, asset, grid, etc)
* DEV: This refactoring is far from complete - only just enough to makes the "show uptime" command common accross the servers.  More is needed, but in this case it's somewhat like eating cabbage, which I prefer not to do all at once
