Convert ambiguous date into standard format.

Sorry to be picky, but I got bitten by some ambiguous date format problems recently so...

The date I am converting (9/6/19) is Sep 6th if it is in US format and is June 9th for all other English speaking countries (I'm highlighting English countries only because this text is in English).  I determined that it is US format by looking at the date of the commit.

I suggest that stuff like this use [ISO 8601](https://en.wikipedia.org/wiki/ISO_8601) format because it is unambiguous, it is popular amongst developers, it is getting wider adoption, and it is a great format!  Thanks.

Define that NVM_PATH is for nvm

Make admin prompt, need to uninstall old node/npm more obvious

Just adding some headings etc

os.Rename() - "Access is denied" error when moving npm from temp folder is swallowed

executables should be binary

Updated build tools. Now supports links to elevate.cmd and elevate.vbs when using nvm root (fixes #381).

Added note about code-signed executable.

Added attribution for @s-h-a-d-o-w.

Add CodeTriage badge to coreybutler/nvm-windows

Make sure file handle to 'node.exe' is closed after scanning for bytes

Fix install.cmd

Updated README.md

Fixes #41 - Issue with blank spaces in path

Forgot some uses of exec.Command() outside of the "use" command.

exec.Command() can't handle spaces, even when quoted.
Command has to be modified using SysProcAttr.
