trailing whitespace cleanup
move secondbase migrations out of db/migrate

rails 3.2 checks subfolders of db/migrate/{secondbase_folder} so
secondbase can no longer live in db/migrate. instead we will no place
the secondbase folder under db/{secondbase_folder}
fix migrations and documention for move from db/migrate
clean up dependencies and depend on Rails
Look for second base.yml if the second base config is not nested in the main config
Update to reflect changes in rake 10.1
revise the module level configuration parsing to look a little more like ActiveRecord::Base
change all of the other places in the code to use the module level connection information
so they don't assume that it is nested in the base configuration
add a drop database task
Merge branch 'rails32_prep' into rails32_compatible

Conflicts:
	lib/secondbase/tasks.rb
