Title: Switch DataMapper to Sequel

DataMapper has not been maintained for a long time, and it is broken on jruby because the new jdbc-sqlite3 gem is released.
In fact, our one test has been broken by using the DataMapper fixture.
I think we should take this opportunity to switch DataMapper to Sequel.

What do you think?
