## Description
Exchange events were amended to use calendars
as a folder structure. This updates the selector
to treat events as having folders similar to mail and
contacts.

The filters package allows callers to specify both a target
to match on, and behavior of the comparison. While data-
type scopes always equate to "equals", the control over
different comparison behavior is useful for info-type
filters. This change integrates filters into scopes for
built-in control of those comparisons.
Though enumerated as ints, the selector service
categories are stored and managed as strings. The
only time that we use the int is when passing their
iota const to and from functions. Using a string
type instead of an int allows us to get rid of the
string builders and AtoI funcs (though not the
stringer requirement in the Iface, sadly).

Leave some sub-packages out that have higher churn at the moment.
Scope production was still using service-type specific
factories instead of a generic factory set. This has been
centralized so that all service instances share the same
scope production concerns.
Additionally, category comparator funcs now use generic
comparators as well, which allows for the removal of the
isType() and includesType() comparator funcs.
Scope filtering is currently hardcoded to the exchange
use case. In order for future work to rely on boilerplate
rather than re-writing the full filtering logic on each new
type, as much of that code as is possible has been moved
into a generic toolset.
Centralizes as many of the exchange scope funcs as
possible into scopes.go. Ensures exchangeScopes comply
with the scoper interface. Reshuffles some test helper
code in selectors to a centralized file.
