[xwiki-devs] Commit for the plan of this week .GSoC-"Auto-completion in content editors"

In this commit, I Implemented the function that logs a message in the firebug console whenever the caret is after [[ (but just that, nothing more!). It contains two small commits, one if the codes for LinkSuggestor, and the other is the test codes for it. -- Best wishes, 许凌志(Jame Xu) MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University
