* Fixed a problem with Database->insert_or_update_variables() where variable_source_uuid being set to an empty string wasn't converted to NULL.
* Fixed Database->locking() where the way the lock variable was set was rather broken.
* Created Striker->check_httpd_conf() which configured apache to handle the integration of the new WebUI for Anvil! management with the existing WebUI.
* Updated System->update_hosts() to specifically set the 127.0.0.1 and ::1 lines to handle how cloud-init overrides /etc/hosts and breaks CI/CD tests.
* Removed the old index.html as it's now used for the new WebUI.
* Began work on removing DB connection requirements from ocf:alteeve:server.
