This PR is taking ridiculously long to be merged for no important reason :-)

@mwillbanks you've mentioned you have `./bin` dir, but what about your `./vendor/bin` which is created by composer ?

@weierophinney My opinion is that we should add both:

 * `./vendor/bin/zf` to main `zf2` repo
 * `./zf` to ZendSkeleton

This way both groups of users will be able to access the app in a consistent manner and we'd be able to standardise it and use it in documentation.
