Overhaul searching/segmenting

[Jericho]

The goals are:

• Consolidate the query for searching contacts, searching email activities and segmenting (currently we have "legacy" query logic for searching email activities)
• Allow using custom fields when searching/segmenting contacts. I wasn't aware this was allowed due to the documentation not being very explicit but @NEMA-IT informed me that it is possible to use custom fields. He is currently contacting SendGrid support to try to get an authoritative confirmation that this is allowed.

This will be a good opportunity to simplify the syntax:

Instead of:

var searchCriteria = new SearchCriteriaEqual<ContactsFilterField>(ContactsFilterField.LastName, "Smith");

we will be abel to write this:

var searchCriteria = new SearchCriteriaEqual(ContactsFilterField.LastName, "Smith");
