VTS: Allows entering primary party codes in different case

[Guy Lancaster <glanca@dieboldes.com>]

  I have no idea why this seems to be new but I just
manually fixed a VTS database in which one of the races had
been entered using an upper case REP party code while the
rest were lower case.  This caused the AV to return a
properly marked ballot as cross voted.  Is it true that up
until now everyone has been consistent in the way they
entered the race party codes?

  This should be fixed in future releases of both VTS and
the AV.  VTS should convert to a single case probably
according to how it's defined in the registration codes
although simply forcing upper or lower case on download
would support all current AV releases.  Future releases of
the AV should be case insensative.
