fixes #982. seed refactor to reduce memory allocation when YUI core modules should not be served from local server. Clear separation between YUI core modules and app-level modules (including synthetic modules). As part of the separation, the seed will have, at least, 2 files, YUI Core Seed + App Seed. Support for relative path when using mojito build command.
