[CDBI] column case sensitivity (Pg)

Hi all,
The postgres database i work on unfortunatly makes use of case sensitive 
column names. It was a wrong database design decision (not by me thankfully), 
i wish i could just change column names but it just breaks too much in the 
interface to do. 
I'm really impressed by the functionality of ClassDBI but unfortunatly 
ClassDBI doesn't work with column names with uppercases in it. I took a peek 
at the ClassDBI code and found that it is quite trivial to make it work with 
case sensitive column names, basically i just removed all conversions to 
lowercase.
I've listed the changes below, unless there is a good reason to have ClassDBI 
only work with lowercase column names maybe this could be incorporated in the 
main branch of ClassDBI? That way anyone can have a lousily designed database 
and still use ClassDBI...
Kind regards,
Erik
