Added getProfiles() for getting more than one profile at once by ID.
Made `getProfiles` a bit more friendly, and `getProfile` an alias for returning a single record.
Changed result keys to camel case, made `getProfile` and `getProfiles` return only a single object when there's one result instead of an array with one item. Updated readme.
Changed version to 1.0.1 after merging in `multiple-ids` branch.
