Fixing bug 393928. Lazily initialize liveconnect, and only initialize it when we can't find a Java plugin that supports NPRuntime. When a Java plugin that supports NPRuntime is found, use NPRuntime to expose liveconnect functionality (i.e. window.java and window.Packages). r=cbiesinger@gmx.at, sr=bzbarsky@mit.edu, a=jonas@sicking.cc
