/*
ProjectItemsRenamer.jsx
version 1.7
(1.2 corrects unemptied variables, causing past renaming to be added to current operation)
(1.3 fixes evil while block with endless loop in some situations)
(1.4 fixes even more evil while block with endless loop. Sorry about that.)
(1.5 removes truncation for app version CS4 or later)
(1.6 search/replace now custom function, for various reasons, including my own mismanagement of files;
                                         the ultimate happy outcome is that renaming is now bug-free!)
 v1.7 replaces dangerous parseInts with parseFloats (because of radix feature in parseInt)
