Replace file in Resources editor.

In the resource editor, it is possible to rename a file from the contextual menu.
It will be nice if we can have another entry in the contextual menu to replace the file with another. Basically the bottom should open a select file dialog. The selected file should replace the selected entry in resource file.

Example:
I want to replace png files to svg. So I can use the rename function.
But when I change the "pdf.png" file to "pdf.svg" file, the resources editor marks it as not existing (in red).
I know I put a new pdf logo file but I can't remember the name, so I open the "replace dialog".
I select my file (as my system is providing icon preview). The file name is "pdfLogo.svg".
Then "pdf.svg" becomes "pdfLogo.svg".

Extra feature, having an option that make pdf.svg an alias for pdfLogo.svg, would be cool as well.
