Since it makes a lot more sense for the default to be *no*
external dependencies, I've flipped it around:

By default, mysql-native is now Phobos-only and does *not* depend on
Vibe.d (or any other third party lib).

To enable the optional Vibe.d support (which also makes Vibe.d sockets
the default instead of Phobos sockets, although you can explicitly
choose either at runtime), then include the following compiler flag:

  -version=Have_vibe_d

That flag above will be included automatically if you compile using
DUB, and your project uses Vibe.d.
