* Modified SQLite/SQLiteInventoryStore.cs to not throw if the inventory row does not exist, to match the mysql behavior. * Modified SQLite/SQLiteRegionData.cs to only persist temporary items following the same rules mysql uses. * Added another ignore to the inventory test that was missing. * Added a few more ignores to the RegionTest that the first version of my test were missing. * Added ignoring the root Folder ID, which is set by the inventory system. * Added several improvements to the PropertyCompareConstraint: Protection against infinite loops, added IComparable<T> (for UUID) and moved IComparable before the property matching. * Fixed a bug where I was saving the inside of the ignore expression instead of the outside of it.
