Introspection Format

[blond]

Example of new format:

{
    button__text: [
        {
            entity: { block: 'button', elem: 'text' },
            tech: 'css',
            path: 'path/to/file.ext',
            level: 'path/to/level'
        },
        /* ... */
    ],
    /* ... */
}

With this introspection format to easily get a list of files named entity.

What has been done?

• Use bem-walk to scan levels.
• Use bem-naming to get id of BEM entity.
• Add BundleIntrospection class to work with introspection of levels.
• Rewrite levels tech with build-flow.
• Use promises with node.buildState to avoid scanning the same levels multiple times.
• Support new format for levels-to-bemdecl, files, deps and deps-old techs.
• Don't read files for directories (example i18n), it should do files tech.

Протестировал сборку: в project-stub и на СЕРПе дифф в сборке отсутствует, в islands отличается только сборка unit-тестов (из-за технологии levels-to-bemdecl).
