Search and Update/Delete contact by name instead of database _id

@flyg101 would be a nice addition. Once sticky note to be aware of is that search query returns case-insensitive inexact result

Considering values are stored in the database as lower case strings, it shouldn't be much of a problem. Extra steps can be taken if multiple contacts are returned from the query

Sure, you'd considering also that we don't have unique constraints lest you delete/update all fields that match.
