- Renamed the variable names to something shorter, and I hope

    nicer. Also, I grabbed my copy of the Informix manual, and
    added a couple of variables that make sense (formats for
    money, time, a language setting, a timezone).

  - New functions SetPGVariable() and GetPGVariable() in tcop/*.
    These don't actually do anything for the moment, but should
    be enough to implement the SET var_name TO var_val in the
    parser?

    SetPGVariable() expects just two strings, the var_name and
    the var_value from above, and is expected to do the right thing.
    Returns TRUE if  everything okay.
