New Search Indexing Support

Plan is to introduce a global index that holds semantic information rather than filename mappings, supports reliable error detection, and is extensible enough to replace all current indexes and caches. It will support most common JDT operations without the need to ever open a .jar file or perform an exhaustive search. The design document is available here
