No more ambient modules for tns-core-modules/* subpackages.
- Use path mappings in tsconfig.json to resolve module typings - Only use ambient mobules for global API's - Move single-file modules to a subdir with the same name so that we can provide a hand-written typing next to it (via package.json) - Delete all mentions of tns-core-modules.d.ts - Delete reference d.ts assembly build steps. Not needed anymore. - HACK! Use a <reference> for global typings in application.d.ts to avoid publishing a separate @types/tns-core-modules package. - Rename declarations.d.ts to tns-core-modules.d.ts to preserve JS project mappings in references.d.ts (the only place we use those)
