Upgrade npm to 1.1.3

* Update request to support HTTPS-over-HTTP proxy tunneling
* Throw on undefined envs in config settings
* Update which to 1.0.5
* Fix windows UNC busyloop in findPrefix
* Bundle nested bundleDependencies properly
* Alias adduser to add-user
* Doc updates  (Christian Howe, Henrik Hodne, Andrew Lunny)
* ignore logfd/outfd streams in makeEnv() (Rod Vagg)
* shrinkwrap: Behave properly with url-installed deps
* install: Support --save with url install targets
* Support installing naked tars or single-file modules from urls etc.
* init: Don't add engines section
* Don't run make clean on rebuild
* Added missing unicode replacement (atomizer)
