mod_ogp/README: Annotate example as XML to enable syntax highlighting

mod_ogp: Add the ability to whitelist domains

mod_ogp: Add the ability to detect and process multiple URLs in a body

mod_rest: Fix syntax error in previous commit

mod_rest: Revert leftover of unfinished ?query mapping Idea was to allow second level data fields to be passed as query parameters, i.e. /rest/command/{to}/?command=execute&node=foobar but that's still a work in progress, so reverted here for now.

mod_rest: Add schema for errors I forget, are these util.error objects in the json mapping?

mod_rest: Support GET for certain IQ queries Example: GET /rest/version/example.com 200 OK { version: { name: "thing", version: "1.0.0" } }

mod_rest: Add more REST-looking way to send stanzas Example: POST /rest/message/chat/juliet@example.net { body: "Hello" } Becomes equivalent to POST /rest { kind: "message", type: "chat", to: "juliet@example.net", body: "Hello" } Sending messages as plain/text also becomes more convenient. IQ stazas are still weird, but we'll do something special for those.

mod_rest: Restructure API spec To make referencing individual fields easier, apparently some things don't like references to individual properties of an object.

mod_muc_http_defaults: Schema corrections
