Support "open with" dialog.

Right now in PA if you try to open a file (double click) in an archive that doesn’t have an active file association, PA simply gives you an error. I think it would be better if it opened up the Windows Open With… dialog as you would get by opening the file from a folder. I don’t think it would be too difficult to implement since it’s basically a feature of the OS already. I know the current suggestion is to create a mapping for the file in Windows, but this isn’t always plausible. Alot of source distributions for example will have README style text files with no extension.

Interesting… in fact, PA was the first to implement Open With in right click menu inside of app itself :-).

good one.
