async-some@1.0.1

Simple refactoring.
github-url-from-username-repo@~1.0.0

Also includes:
* normalize-package-data@1.0.1
* npm-registry-client@3.1.5
* read-package-json@~1.2.7

Treeish names containing slashes now work. Also pulled dezalgo up to a
top-level dependency, which necessitated adding it to the
bundledDependencies list.
