This fixes a bug where TUs and devs couldn't upload packages because
the query would have an extra column in it to mark the pkgbuild safe
automatically, guessing it got missed when the safe flags were
removed. Also fixes a screw up I made with the schema file when I
added the tables for the voting app.

Simo's original commit text:
 The idea of safe flagging is unclear, poorly named, misunderstood,
 and not even used. At the time this patch was created, less than
 a third of the packages in unsupported were flagged safe, and less
 than a tenth of users knew how to interpret it.

 The safe flag has been replaced by a disclaimer on the main page.

Added AUR_VERSION to config file, so now we should only need to
change one location. KISS ftw.

list package name in green on the package list page (with legend)

Implemented ModifiedTS such that:
  -ModifiedTS changed ONLY when package updated
  -SubmittedTS changed ONLY when new package
Also made DummyPkg fixups in tupkgupdate

Also fix issue where orphan was generated if a dummy is
replaced and "overwrite" wasn't checked
