Alts Toolkit: Add consistency check for DEL and SPL pipes

Some modelers are resorting to using Access and MapInfo to access the back
end of the Alternatives Toolkit to copy alternatives from one model to
another.  On one occasion, the MdlLinkID of a DEL pipe turned to zero, and
the Alternatives Toolkit would report that the LinkProcessor could not open
the mdl_links_delete table (line 117: Select * from mdl_links_delete Where
LinkType <> "X" Into delete_failed).

Possible solutions:
  * Enhance the error message
  * When applying, notify the user that a DEL pipe has a zero MdlLinkID and
option to ignore during processing or ability to change it during processing
  * When opening an alternative, perform consistency check for DEL and SPL
pipes with zero MdlLinkID
  * Add a copy alternative from other model feature (complex)

This is not a high priority since not many users do this (yet).
