string to char*

[Andrej Mitrovic]

I'm interfacing with Scintilla (C++), but it works in a different way.
It uses messages, which allows it to be linked with practically any
language. But I can still pass parameters to be modified by passing
the address of the variable instead (the wrapper takes care of that).

Although linking with C++ is difficult, having proper C linkage is a
great thing. There's a ton of libraries out there ready to be used
right now in D.
