Add general async support for LS operations


Add async support for CRUD and Querying capabilities for the following:

SaveChangesAsync() - Performs all syncing using async DB operations QueryAsync() - Create a queryable that performs async FindByIdAsync() Etc....

These would all be awaitable and return a task. There is already a suggestion for Querying that could be rolled into this.

The obvious downside is that you'd have to have a distinct 4.5 version to use the awaitable methods in ADO.Net unless you wanted to take the old school async approach.
