Changes to readme-burning-isos

[Eric "Sparks" Christensen]

I was checking a few of my guides and noticed there was a problem with
the translations coming in on readme-burning-isos[1].  Apparently a
few changes were made but the POTs and POs weren't updated.  I just
updated the POTs and POs which created five "fuzzy" lines over three
files: Validating.po, Downloading.po, and Next.po.

I appologize for the mix up.
