Fix the behaviour of sql classes regarding quoted identifiers
If no quotes around identifiers are provided by the programmer,
identifiers are treated identically to how the underlying engine
would behave. i.e. some engines uppercase the identifiers
others lowercase them. If the programmer wants case sensitivty
and/or use whitespaces they will need to quote their identifiers.
The previous (incorrect) behaviour always quoted the identifiers.
