Add the ability to allocate extra per-dialog-instance private data

Browse Source 
in the portable dialog interface. This has allowed me to remove
`ssd->savedsession' in config.c, which was (I believe) the only
out-of-place piece of per-instance data in the dialog template
stuff. Now we should actually be able to run more than one config
box in the same process at the same time (for platforms that'll find
that useful).
