Remove addins
Switched the tolerance for dictionary key comparison to new Tolerance(0) from Tolerance.Empty so that numerics do not take the default system tolerance. Added tests for non-generic IDictionaries and fixed those in NUnitEqualityCompare.

Fix for issue #45

- Renamed UpTo to Until
- The test now runs when the Until date has expired
- Added an IgnoreUntilDate property that gets set
- The date and/or time is specified in UTC. If no time is given, it defaults to midnight UTC.
- If no reason is given, it is set to "Ignoring until yyyy-mm-dd hh:mm:ssZ"
- If a reason is given, it is not altered since that information is in the IgnoreUntilDate property.
