adduser: allow change of the saved password

Modify `npm adduser` to allow the user to change the password used
for authentication. This is useful when the password was changed
via the website and the user wants to update local npm config
to use this new password.

Before this change, `npm adduser` would not ask for a password when
the username was not changed, thus it was not possible to easily
change the password while keeping the same username.
adduser: Clarify password prompt

When there's the option to leave it unchanged, the prompt should reflect
this.
Check SHA before using files from cache

Fixes #3265.

Because 'npm install' *always* writes every package to the cache (even
if it isn't installed from the registry) before installing it, it's easy
to end up in a situation where "npm install foo" installs something
other than the appropriate version from the registry.  eg:

  npm cache clean
  # Install a fork of version 0.0.1:
  npm install https://github.com/glasser/npm-cache-corruption/tarball/93c447e
  rm -rf node_modules
  # Before this commit, this would install the same fork as above
  npm install npm-cache-corruption
