fully functioning and (as far as I can tell) specification compliant server server accepts json objects or regular GET requests (important as both handle multiple 'rel' key's in one request) server storage schema moved to fully file based, scrapped sqlite code for the time being. server-manager added for the creation and manipulation of resources server-manager accepts json onbjects for complex operations or regular POST requests server manager is authoritative and secure server-manager can add and remove hosts (which must be configured before adding resource accounts) and resources server-manager can manipulate various data in the resource accounts (currently alias data, subject and properties are WIP) server-manager can alter account password rebranded from PHP-Webfinger to PHP Easy Webfinger Server (PEWS: Pew-Pew) created logo and favicon (intended for a web-based manager frontend) ships with apache config file for the management of multiple domains on a single server
