[TYPO3-dev] t3lib_TCEmain: quotes around column names

[Christian Kartnig]

Hello!

I came across an issue with copying records in t3lib_TCEmain: An 
extension uses the reserved keyword 'sql' as a column name, which throws 
an sql error when copying records in the list module (with mySQL5).

Maybe it would be a good idea to quote all column names with backticks 
to avoid such problems. What do you think?

regards,
Christian
