want to use for web actions without using the browser's protocol
handler. Add discover_endpoint function to microformats.php and
remove duplicated code from Post and Indieauth modules. This function
is now also used by webaction.php which will return the config of
local users and perform webaction endpoint discovery for others.
Indie-config no longer checks for the web+action protocol handler,
instead what was a fallback dialog is now shown straight away. A user
can enter a url to perform webaction config discovery.
Members module now reloads data when visibility of supplier and
active columns change. SimplePie get_id can't use full content in
hash because content can change on every page reload.
