pgAdmin III commit: Revert the previous change that introduced sysSetti

Revert the previous change that introduced sysSettings::WriteBool(),
and restore the previous Write() overload. Whilst the change was, in
theory, good, it failed to take into account that users of previous
versions of pgAdmin would have true/false values stored in the
Windows registry as REG_SZ values of "true" or "false", not REG_DWORDs
as the new code would write. Needs more thought, and thorough testing
on Windows when we re-visit this.
