Changed logging of SQL statements to use the DEBUG level instead of INFO. Added logging of the request URI in the benchmark statement (makes it easy to grep for slow actions). Changed the default logging level in config/environment.rb to INFO for production (so SQL statements won't be logged)

Eager loading of dependent has_one associations won't delete the association #1212. Also, starting to refactor the tests to make them speedier, with optional support for transactional fixtures.


git-svn-id: http://svn-commit.rubyonrails.org/rails/trunk@1398 5ecf4fe2-1ee6-0310-87b1-e25e094e27de

Added a second parameter to the build and create method for has_one that controls whether the existing association should be replaced (which means nullifying its foreign key as well). By default this is true, but false can be passed to prevent it.
