[Midas] "manage data export"

[Patrick Reynolds]

In some circumstances you may want to create hard links ($ ln) instead
of symbolic links ($ ln -s), that is what the checkbox signifies.

Hard links have limitations, of course, including the inability to
link directories or span file-system boundaries. When in doubt, use
symlinks.

Midas will then export symlinks to the assestore locations of each bitstream in a manner mimicking the hierarchy within Midas.
