Update to Sequel 5.0.0

[ckoenig]

Since Sequel 5 immediately attempts to connect to the configured database, the development DB sequel_rails_test_storage_dev needs to be created, too.

Adding the following two lines to .travis.yml will hopefully fix most of the failed tests:

- mysql -e 'create database sequel_rails_test_storage_dev;'
- psql -c 'create database sequel_rails_test_storage_dev;' -U postgres

The sqlite3 tests are failing because SequelRails::DbConfig#build_url converts a relative path into an absolute path. Combined with the fact, that Sequel 5 is now eagerly trying to connect to a DB, the test fails.

To fix the test, it might be enough to replace the relative with an absolute path in the Rakefile:

diff --git a/Rakefile b/Rakefile

@Jesterovskiy Thanks a lot for the amazing work!

I'll take some time to review and merge in the next couple of days.

Thanks @Jesterovskiy for the good work, I'll merge the request and change the dependencies to deps to work with Sequel < 6.0 as @bgentry suggested.

@JonathanTron Thank you! Now you can release this, right?
