	1. Make a practical file cruncher.  REM has done a good part of
the work some time ago.  Perhaps it needs the syntax
CRUNCH <FILE NAME> ← <LIST OF FILES>
The result is a crunched file and a table of contents.  The latter may
be part of the same file or more feasibly a file with the same name
and a different extension.  So we get FOO.CRU and FOO.CON.
There needs to be a command that might take the form
UNCRUNCH BLA.F4,BAZ.PUB ← FOO
which extracts BLA.F4 and BAZ.PUB from FOO.CRU.  A switch determines
whether FOO.CRU remains as is or has BLF4 etc. deleted from it.
One may want to allow name change in the process of extraction.
It would be best of all if crunched files remained in the directory,
but this would require a change to SKSER.

Qt is assumed that people would be told a ratio between disk
space and computer time and would be encouraged to make their
crunching occur in the middle of the night.
