0.1.5

added better compatibility for newer implementations of IndieAuth; for now, we default back to the old behavior, but you can switch to the new implementation by setting the config options 'endpoint-discovery-via-header' and 'indieauth-metadata' to true. This will automatically become the new default in a future release.

• new config option to hide link previews (to hide link previews, use 'link_preview' => false)
• new config option to disable auto-link-detection in post conten (to disable auto-link-detection, use 'link_detection' => false; this will also disable link previews)
• added support for endpoint discovery via http header; set the config option 'endpoint-discovery-via-header' to 'true'; this will become the default behavior in one of the following releases
• added support for indieauth endpoint discovery via 'indieauth-metadata'; set the config option 'indieauth-metadata' to 'true'; this will become the default behavior in one of the following releases
• the 'auth_mail' config option is now deprecated and will be removed in a future release. use the following config option instead: 'rel-me' => 'mailto:mail@example.com'
• if you want to use the indieauth.com login in a future release, you need to set the following config options:

	'authorization_endpoint' => 'https://indieauth.com/auth',
	'token_endpoint' => 'https://tokens.indieauth.com/token',
	'rel-me' => 'mailto:mail@example.com',

• added template name to body-class ('body.template-index' for overview, 'body.template-post' for detail view ..)
• better general compatibility with IndieAuth
• add_header() & remove_header() functions, to set http headers
• bugfixes & enhancements
