Update from version 1.21 to 1.24.  Changes:

1.24 2008-07-09
	- Ripped out all 1.23 changes
        - Re-releasing 1.22 with DBIx::Class as maintainer

1.23 ????-??-??
	1) Large patch by Laurent Dami to add all of the
	following functionality:

	 - support for nested subqueries (see the doc for explanations)
	 - +/- prefixes in C<@order> columns, meaning 'ASC' or 'DESC'
	 - documentation :
	    - added an explanation about flexibility of argument types
	      (passing scalars instead of hashrefs/arrayrefs)
	    - added an example of a boolean column (through ref to empty
	      string)
	    - mentioned that select() can take an arrayref of tables
	    - added explanation of +/- prefixes in C<@order>
	    - WHERE section structured into subsections
	    - new subsection for nested queries
	    - suppressed the NOTES section about Morgan laws, because
	      subqueries provide support for compound logic statements.

	These changes enable additional functionality in DBIx::DataModel
	as well.

	2) Patch by Robbie Bow to enable "quote_char" to take
	an array ref.  This fixes an issue to MS SQL Server,
	since it requires that columns and tables be quoted with
	surrounding [square brackets]

	3) Patch by Norbert BUCHMULLER to enable the use of
	the old-school-SQL operator for not-equal ('<>')
	could be used for the 'IS NOT NULL' expression:

	  foo => { '<>' => undef }

	This now properly generates:

	  foo IS NOT NULL
