Consolidate environmental initialization

Browse source 
Summary:
We have a bunch of code duplication now between __init_script__.php and webroot/index.php. Consoldiate these methods and move them into PhabricatorEnv.

Merge PhabricatorRequestOverseer into PhabricatorStartup.

Test Plan: Loaded page, ran script. Wiped PHABRICATOR_ENV; loaded page, ran script; got errors.
