Added case insensitive options

[kriszyp]

Adding better support for case insensitivity sounds good. The concern I have about this particular approach, is that I am hesitant to make queries be more context-sensitive. Generally, I think a query should fully and explicitly specify what matches and doesn't match, and with this approach a query behaves differently based on store configuration. And this also would make it difficult to have queries with mixed behavior (some properties case sensitive, some note).

For sorting, I think it would be quite reasonable to simply add another property to the sort objects that would specify case sensitivity.

For filtering, I would like to make the query building capable of handling this. Currently the Memory store should support {property: /^aNyCaSe$/i}. Of course, we have incomplete support for this, since presumably the Request may serialize this poorly for the query parameter.

This is now old... The way queries are made is completely changed.
