download link error

[gusyang]

for v4.1.0,
when use nvmw install v4.1.0, the bat file build link is https://nodejs.org/dist/v4.1.0/x64/node.exe
but real link is "https://nodejs.org/dist/v4.1.0/win-x64/node.exe"

The same issue.
I changed this string
set NODE_EXE_URL=%NVMW_NODEJS_ORG_MIRROR%/%NODE_VERSION%/x64/node.exe
to
set NODE_EXE_URL=%NVMW_NODEJS_ORG_MIRROR%/%NODE_VERSION%/win-x64/node.exe and it works.
