Remove Configsettings from cached data

We are actually caching the "Configurations" list to the database even though we are overwriting it every time we pull from the database. We need to do one of 2 things: a) the simple approach is to exclude "Configurations" from the data we are writing to the DB (I think a simple "[Ignore]" directive would work or possibly a custom NHibernate mapping definition, or b) see if we can cache this to the DB on initial Login and then just use that cache rather than pulling from the DB as often (we would still need to reload Configurations on a "ChangeStore" as they are Entity-specific)
