Change format of name for "contributors to digital file"

[kmcmullen]

As we discussed at Chesnutt Camp, we would like the "contributors to the digital file" (listed at the bottom of each item) to appear in FIRST NAME LAST NAME format, rather than the current LAST NAME, FIRST NAME. So, we want Kevin McMullen, not McMullen, Kevin.

The names are currently being pulled from the respStmt; the correct format of the name is found in the revisionDesc, but duplicate names will need to be removed, as people are sometimes listed there more than once.
