Removed NUI shortcut.

We're not going to have a shortcut for NUI anymore. There are individual flags related to NUI that are controlled in CallLogConfig.

Other related changes to help accomplish this:

-Changed how the call log framework/config/migrator interact; the migrator is now only called on config changes and enabling/disabling of the framework now lives in CallLogFramework.

-Move CallLogConfig an interface, and moved it to its own package and added component and module. This is to simplify tests which just need to check the config status (like PhoneLookupHistoryRecorderTest).

-The "Main" package is also on longer needed since it existed to control the shortcut.
