yage e199e9bf91 v3.5.0
=====================================================================

--- Changes ------------------------------

- AWS (the cli wrapper) now checks for it's required variables *on run*.
  This accomodates scwrypts which may need to run in multiple regions,
  but make the downstream scwrypt responsible for adding AWS_REGION to
  the REQUIRED_ENV list!

- Got rid of all kinds of hackiness surrounding postgres password evals
  between both the postgres library and the rds library

--- Bug Fixes ----------------------------

- scwrypts --update now pulls tags for proper versioning
