. Optimize ApplicationScriptUtils.toJSON() - threadlocal cache for namespace resolution to avoid DD access, smarter retrieval of cm:person properties - 40% quicker or more in some cases

Browse Source 
. Convert short qnames to long qnames in our templates to avoid DD access to resolve full qnames
. Optimize out N+1 queries from calling RatingService.getRating() unless the document has at least one Like (which is available in the rolled up property already present on the node) - up to 99% quicker when building "Likes" JSON structure...!
. Added new optimized method to FileFolderService to retrieve a cm:name based path - only the String for each path element not the full FileInfo structure for each (avoid full getProperties() - 70% quicker to build webdav URL
overall before/after to retrieve doclist2 script (8x concurrent threads x25 repeats etc.) Before: 1030ms After: 645ms
Also improves original doclist script (used by dashlets) and single node retrievals.
