Merge lp:~dedzone/drizzle/ded-decimal into lp:~drizzle-trunk/drizzle/development

[Djellel E. Difallah]

Have just merged decimal and my_decimal, and updated the references then tested it.

[Monty Taylor (mordred)]

Wonderful. Looks like you left in a commentted out section of code:

 +//#include "drizzled/error.h"
 +//#include "drizzled/field.h"

Could you remove those? Otherwise, looks fantastic.

review: Needs Fixing

[Monty Taylor (mordred)]

Awesome. Looks great!
