Several changes to the DB system:

Made all schemas subclasses of WeBWorK::DB::Schema, factored common
constructor code out into Schema.pm. Made all drivers subclasses of
WeBWorK::DB::Schema, factored common constructor code out into
Driver.pm.

Removed superfluous style() and tables() functions from schemas and
drivers. (You can treat the constants in which these are defined as
functions, and call them like $object->STYLE or $object->STYLE().)

WeBWorK::DB now tries to build all tables defined in %dbLayout, instead
of using its own internal list. (TODO: add warnings if known tables are
not built or unknown tables are built.)

Made the error messages given during DB instantiation a little more
intelligent.

Changed the behavior of the exists() and delete() schema methods in all
schemas (and updated the docs) s.t. not all elements of @keyparts have
to be defined.

Changed WeBWorK::DB to allow undefined values to be passed instead of
IDs in delete* method calls, but only if the call was made from
WeBWorK::DB itself (to protect you from accidentally passing an
undefined value and clobbering your whole database).

Changed delete functions to be more efficient. For example,
deleteGlobalSet no longer has to say:

	$self->deleteUserSet($_, $setID)
		foreach $self->listSetUsers($setID);
	$self->deleteGlobalProblem($setID, $_)
		foreach $self->listGlobalProblems($setID);

Instead it says:

	$self->deleteUserSet(undef, $setID);
	$self->deleteGlobalProblem($setID, undef);

This is somewhat more efficient with hash-style schemas, and MUCH more
efficient with the SQL schema.

As usual, be wary of lingering bugs. w00t!

Added the capability to the GlobalTableEmulator to designate a user
whose records will be used as global records. To specify this, set the
globalUserID param for the tables using the GlobalTableEmulator (in
%dbLayout). It's probably good to do this on a per-course basis. Put the
following in your course.conf:

	$dbLayout{set}->{params}->{globalUserID} = "professor";
	$dbLayout{problem}->{params}->{globalUserID} = "professor";

If globalUserID is not present, GlobalTableEmulator will use consensus
(which is very slow!).

Made listGlobalProblems more efficient. (I have to go back and look at
the rest of DB and see if there are any more optimizations that can be
made.)
