Updated SQL Server "Message" field length to match other DBs. Add "AppName" argument to "notifyService".

I had some bugs that I was trying to log with the default CF message. They were failing to be processed in the queue. It was because they were around 300 characters. And for some reason the SQL Server scripts specify "Message" as half the size of the others. So, I updated both SQL Server scripts.

I also needed to be able to call "notifyService()" with an application name. So, I added a cfargument that is defaulted to what was being used. This should be totally backwards compatible.
