Waterline incorrectly sees search for as value of 'OR' as the 'OR' operator in some cases.

Nobody has claimed this yet.

There appears to be a bug in waterline that can in some cases cause it to misinterpret an 'OR' in a value as an operator.

This code works as expected when searching with only the state.

```
sails> Address.count({state: 'OR'}).log()
Running with `.log()`...

It also works as expected when the state is not 'OR':

```

I believe the problem is to be found in sequelizer.js, and might have something to do with options.strip, but I couldn't find anything describing how to use those parameters so I didn't want to go any further with it than that since I've never used knex directly.

Reproduce the failure with Address.count({city: 'PORTLAND', state: 'OR'}) and compare it with the working state-only and non-OR searches. Inspect sequelizer.js, especially the options.strip handling mentioned in the report; done means the OR value remains a value and the combined query succeeds without the undefined-operator error.
