Bug 23623 – On 64 bit Windows the path should point to 64 bit dmd.

The NSIS installer for windows has the option "Add to PATH". When this option is ticked, the system path is modified to include "C:\D\dmd2\windows\bin", which is correct on 32 bit Windows. On 64 bit Windows, "C:\D\dmd2\windows\bin64" is preferred. The installer should detect the version of Windows and set the path accordingly. Grep for "Target was appended to PATH", which is displayed at the end of the installation.

Since a number of tools that exist in "C:\D\dmd2\windows\bin" are absent in "C:\D\dmd2\windows\bin64", it is probably best to include both in PATH, but "bin64" before "bin".
