Compilation error with DMD head - Switch case fall-through.

[Kapps]

On line 1064 of ddox/internal/demangle.d, the implicit fall through will fail to compile with DMD head. Instead it would need to be changed to explicitly use goto case '0' to fall through to case '0' .. '9'.

I've just removed the file altogether. It was necessary at the time, because a required API didn't make it into DMD in time, but it's included now.
