Multiple versions of dapper collide

[RylanH]

If you have multiple versions of dapper in the same application (i.e. because of npm link), you have to configure one or the other to use a special classNamePrefix. It would be nice if dapper just automatically used different keys.

Options for solution:

1. Use a truly global unique id
2. Use a random value prefix (still could potentially collide)

Looks like a good match to me

It might need some love to insert separators other than :, though
