Visual Studio didn't like the filename with a 1.8.0 in it.  Renamed to
quiet down VS.
Clean up code. Fix the filtering function to work with new entries.

1.)  Move some repeated code to a function
2.)  Add a way to force an update regardless of date of last update
3.)  Fix the filtering function.  It now correctly analyzes new entries
without a queued property.
4.)  Remove some unnecessary, old bits of code.
