Introducing a Scopes Mapper to map from RA scopes to TextMate scopes with fallbacks.

Current scopes defined:
```
    ['keyword.unsafe', ['storage.modifier', 'keyword.other', 'keyword.control']],
    ['function', ['entity.name.function']],
    ['parameter', ['variable.parameter']],
    ['type', ['entity.name.type']],
    ['builtin', ['variable.language', 'support.type', 'support.type']],
    ['text', ['string', 'string.quoted', 'string.regexp']],
    ['attribute', ['keyword']],
    ['literal', ['string', 'string.quoted', 'string.regexp']],
    ['macro', ['support.other']],
    ['variable.mut', ['variable']],
    ['field', ['variable.object.property']],
    ['module', ['entity.name.section']]
```

Need to complement with further fallbacks as some themes fail.
