DfRefactor

It could be quite useful for power users to have a "find & replace" option.

We don't have a find & replace right now. The idea is to add a find&replace dialog with regular expression support (a "regex" checkbox).
This way you would be able to run any regular expression of your liking over the source.

Then you can also "refactor" other things that are not within our scope of updating old code.
We could probably borrow the code from the hammer for the search & Replace dialog and add the regex bits and pieces that we have in our code now.
