Find and Replace function for Bridge

@Shlomit Heymann my new add-find-replace script is ready for testing. It is working well for me, but plase consider it still in development and only work with test copy files. The script is called "Add-Replace Metadata" and will be in the Tools menu.

Click the "?" buttom for instructions. I hope they are clear, let me know.

I added a feature to add the file name. If you enter [FILENAME] in the Add text box, the actual file name will be added. You have to add any punctuation and space you want before or after the filename. In your case, you would enter ", [FILENAME]" (quotes aren't necessary).

The script window will stay open after it runs and you can do additional changes.

I have to say that adding and replacing metadata via a script makes me nervous because things could go wrong and there is no undo option. You might consider exporting all of your metadata to a text file as a backup. I can help with that, if you are interested.
