Would like "File Associations" in Preferences Options

[DSperber]

Presently, the only opportunity I have to set PMView as the default viewer for a particular file type (extension) is at program installation.

But if I would like to change those defaults later (e.g. to make PMView the default viewer for a type I had previously un-checked because I was using another program at that time but now I've changed my mind) I can't get it done without going through a reinstall of PMView again in order to get that dialog presented.

Can the File Association dialog be added to the Preferences notebook?
