Update jsPlumb to a build with the praekelt:jsPlumb#2 bugfix
Wrap the source and target event properties as jquery objects for jsPlumb connection and connectionDetached events in DiagramConnectionGroup (this appears to have changed since jsPlumb v1.4.1 from already being jquery-wrapped objects)
Add our jsPlumb fork's build with the recent bugfixes
Rename jsPlumb build: jquery.jsPlumb-1.5.2.js -> jquery.jsPlumb-1.5.2.praekelt.js
