added support for inheriting development from parent

[mnichols]

This just extends the 'inherit' builder function to persist the 'dev' of the parent so that local deps can contribute their 'development' dependencies.

This seems to fall out of sync with the install of dev dependencies for remote components, causing the lookup to fail. You may feel this pushes the 'development' attribute beyond scope, though local components do seem to need to have this kind of inheritance. Problem is there is not distinction b/w local and remote deps inside builder.

hopefully with #130, you'll be able to require() stuff as long as it's in the bundle. i'm generally against any sort of inheritance.
