Update to 1.50:

1.50 Tue 7 Jun 2011
	- Removed normalize as a supported parameter, normalizing columns turns
	  out not to work in practice. However, we always normalize tables to
	  get the class name for the table as that seems to result in class
	  names that make much more sense.

1.49 Wed 1 Jun 2011
	- Adding normalize support to turn columnName into column_name

1.48 Fri 21 Jan 2011
	- Initial support for shim => 1 to simplify customisation (ADAMK)

1.47 Wed 8 Dec 2010
	- Adding readonly support for views (ADAMK)

1.46 Tue 30 Nov 2010
	- Bumped File::Path dependency to 2.08 to prevent test failures
	  from the one shipped with Perl 5.8.9 (AZAWAWI)
	- Added experimental base class ->update support (ADAMK)
	- Added the qname attributes to the generator structs to simplify
	  and improve readability of SQL fragment strings (ADAMK)
