Add "AppName" argument to "notifyService"

I needed to be able to call "notifyService()" with an application name.
I added a cfargument that is defaulted to what was being used. This
should not change anything for existing installs.
Fixed 1.8 migration SQL error

Removed "COLUMN" keyword. This is not valid and would not run. See sql
server docs. http://msdn.microsoft.com/en-us/library/ms190273.aspx
Updated "Message" field length in the SQL Server scripts to match other dbs.

This is to match the other scripts for the other server types.
