i was getting frustrated because when I extracted the zip to the CWD, i
also had an extra folder level in there called `skeleton-master`. I
started with `laravel/installer` as a base, and that didn’t have that
extra folder in their when downloading and extracting
`laravel/laravel`.  i figured this was handled in the code somewhere,
but **actually** the difference was how where laravel was downloading
the zip from, and how that zip was packaged.

taylor created a subdomain at `cabinet.laravel.com` that holds the
archive for download. if I use the exact same code from `installer` and
download the zip from github, it has the same issue as I am having.

the solution is I am downloading and extracting my `skeleton-master`
package to the CWD, and then renaming it to the package name.
