Elegant way to use dynamic bindings

[Dennis]

I read the Derelict documentation a while ago, I didn't grasp all 
of it. Reading it again, I can now make sense of it though. :)

I added `pragma(lib, "mupen64plus.lib");` above the extern(C) 
block.
Adding `libs "mupen64plus"` to dub.sdl doesn't make a difference.

The thing that confuses me is that the import lib has symbols 
without underscore prefix (I see them when running `libunres -p 
mupen64plus.lib`), but when I change the function pointer 
declaration into a function declaration it tries to link 
"_CoreGetAPIVersions" and can't find it.

I put the .dll's in the root of the project directory by the way. 
Does that count as a "system library search path"?
