The tests now run with rails 4.1.0

removing duplicate standard_dump
Fixed bind type casting to re-set the casted value back to the bind, fixed bind parameter tests to work with SQL server
Added the :authors fixture to AdapterTest to fix a failure in test_select_methods_passing_a_association_relation
Type casting is now happening, so the test regex needs to be updated
The test test_to_sql_on_eager_join was seeing slightly different result in that the SQL was embedded in a call to sp_executesql, which seems ok to me
Rails 4.1 seems to use strings for database config keys nows
Fix how we are checking bind tests, can't use coerce since the test methods are defined in an if block
Fixed tests in rails/activerecord/test/cases/connection_adapters/connection_handler_test.rb by setting the RAILS_ENV to 'default_env'
Unescape quotes from default values
Added support for create_table :as, which fixes tests MigrationTest#test_create_table_with_query and MigrationTest#test_create_table_with_query_from_relation
Clear the schema cache for a table after creating it to prevent a cached negative response - fixes test ActiveRecord::Migration::ChangeSchemaTest#test_change_column_null
PersistencesTest was renamed to PersistenceTest in rails 4.1, so we have to do it in our codebase also
Use Arel::Nodes::BindParam instead of Arel.sql for substitute_at so that ActiveRecord::Relation merging works properly - tests RelationMergingTest#test_merging_reorders_bind_params and RelationMergingTest#test_relation_to_sql
Coerced test for ActiveRecord::PredicateBuilderTest#test_registering_new_handlers since the regex doesn't work for T-SQL
Fixed test NamedScopingTest#test_scopes_honor_current_scopes_from_when_defined by adding a second column to the ORDER BY condition of the :ranked_by_comments scope of the Post model
Added savepoint name param to create_savepoint, release_savepoint and rollback_to_savepoint
