Add utility method to check for DB.IsOnline()

[GoogleCodeExporter]

Please add a utility method on the DB class to check to see if database is
online (can connect to it).

Here's how I'm doing it now:
1. Create a Query object using one of my data tables that has data.
2. Select top 1 row from it
3. Execute it
4. If throw exception, then offline, otherwise is online

signature could be something like:
public bool IsOnline();

I'm sure there's a better way to check to see if the DB is online or not,
but the above sequence is what I've been doing for years when I was just
writing my own SQL Select statements instead of using SubSonic.

I requested it a long time ago, still think is is a great idea. Testing if the
database is only is something everyone does, so why not make it in a unified 
way.
