SPRINTF JS UPGRADING

Original library at https://github.com/alexei/sprintf.js By default the library only supports string placeholders using %s (lowercase) while we use %S (uppercase). The library has to be manually patched in order to support it.

• grab the unminified version at https://github.com/alexei/sprintf.js/blob/master/src/sprintf.js
• update the re.placeholder regexp to allow "S" as well as "s"
• update the switch statement in the format() method to make case "S" equivalent to case "s"

The original changeset adding support for "%S" can be found on this fork:
