A couple new sometimes-handy Dev Tools/SQL scripts
migration to clean up FieldTypes
+ Migration for new BlockAttributes to Notes to make showing the Private, Alert, and security button optional (defaults to visible)
+ Drop IHidableBlock now that we don't need it
fix up ShowInGrid column showing up in wrong position in Grid
Migration to change SubPageNav.xslt path so that it can be used in more than just PersonDetail
Update ZoneBlock name edit field to be wider so the blocktypes with longer names don't get cut off as often
Merge branch 'develop'
