Nested Schema Validation

[clark0x]

Currently, anchor works only for either type(nested type) or ruleset. But I really need nested schema check which combines type and ruleset (means, any type defined in nested type schema can be replace with a ruleset). This PR add Nested Schema Validation, and the code is based on a copy of deepMatchType, I only refactor the old matchType.js and changed anchor.prototype.to() slightly. So it should be backward compatible: this PR pass all old anchor tests , sails#master tests and waterline#master tests, without changes.

But to make nested schema validation works, request.validate() and Model#validate() have to change the way of using anchor.prototype.to(). The former is quite simple, I'll send a PR on sails. The later is too complex, that's why I ensure it backward compatible.

@mikermcneil will this PR be accepted? it's an excellent contribution!

@clarkorz we're working on a more flexible version of some of the basic type-checking here as part of the machine module in the node-machine project-- let me know what you think! Would be good to figure out a way to share some code between modules
