Merge websocket plugin with core
Websocket functionality is currently implemented as a plugin. It should be part of Openfire's core feature set.
so openfire 4.2.1 direct support websocket
The code of the websocket plugin was merged with the master branch of the code (which will be Openfire 4.2.0), after a last update to the plugin was moved into the 4.1 branch. There, the current (and possibly last) release of the plugin lives: version 1.2.1. This version got a "priorToServerVersion" tag as introduced by OF-1353.
