Lift + shift for cross-db macros (#162)

* Initialize lift + shift, dateadd + datediff

* Switch to alternative dev branches

* Lift and shift cross-database macros from dbt-utils

* Switch namespace from `dbt_utils` to `dbt`

* Trim trailing whitespace

* Copy functional tests for cross-database macros from dbt-utils

* Remove references to other profiles

* Kick out the `current_timestamp` + `type_*` macros/tests

* Remove branch identifiers
