Search files on certain volume 2.2.1

Search files on certain volume implements the PBCatSearch function of the Mac OS File Manager. This is a very fast routine to find specific types of files on a volume. The MacOS tool Sherlock (aka Find File) uses this function to do its quick search on volumes.
This plugin also shows how you can allow your RB app to access complex data structures inside the plugin without having to create a REALbasic Control or Class, something that is not yet possible for Windows plugins (the trick is that you create a temporary structure inside the plugin and then provide accessor functions to get and set the individual elements of that structure).
Enhancements:
- Carbonized, works with Mac OS X now.
