cli strips case from package names

[jwebbdev]

mean package myPackage will result in /packages/custom/mypackage, altenatively mean package my-package will result in /packages/custom/my-package, but then not be injectable in the register function of other packages due to hyphens not being valid in variable names. ( linnovate/meanio#58 )

Subsequently, there's not a great way to do multi-word package names. I think both of these should work. The camel case would be a cli fix, while the issues with hyphens would probably be resolved in a combination of cli and mean-io as it would require the cli to give proper camel case names with the DI in linnovate/meanio to not treat the name of the explicitly as the physical path.
