ENH: align dbtypes for forum/group keys

[johnhenley]

Is your feature request related to a problem?

Security and settings keys for Forums/Groups are used in database procedures, and are not using the same database type, resulting in implicit conversion during procedure executions.

activeforums_Settings.GroupKey is nvarchar
activeforums_Security.SecurityKey is nvarchar

activeforums_Forums.ForumSettingsKey is varchar
activeforums_Forums.ForumSecurityKey is varchar

activeforums_Groups.GroupSettingsKey is varchar
activeforums_Groups.GroupSecurityKey is varchar

Describe the solution you'd like

Align these types to be consistent.

As far as I remember, NVARCHAR is always a more flexible option, but these values don't necessarily need the flexibility. This is why I use NVARCHAR for anything that might be localized.

Agreed. No need for nvarchar for these. Easy enough to fix but very low priority.
