[AppDB] - make variables more consistent, fix indenting

There are two issues here

1. large patches/commits are difficult to debug, test and fix.

2. Escaping input does not make the queries safe. We need to implement 
security by making the queries themselves safe.

It may be a pain in the ass for you but it is an even bigger pain in the 
ass for everyone else when things break. With one big patch I cannot do 
a  "CVS update -D" to find exactly where things broke or just back out 
the broken part easily. Also I cannot easily test a monolithic patch but 
I  apply and test small patches. My compromise would be to have no more 
than 4 files changed in a patch unless it cannot be avoided.

Right now makesafe() does nothing because you turned it off.  but with 
it turned on it breaks things and there are still real security issues 
to address. I'm not sure what else is broken at the moment but I know 
that there is some problem  administering the user account's where you 
do not see the users data.

This is exactly why I think we should audit queries.  The "makesafe" 
patch does nothing to address the issues he brings up. If the queries 
are not safe then we need to fix them.  See the patch I sent to you and 
appdb at winehq.org
