Fix closing table tag and TableQuery type.
fix test
JSON sample
Merge branch 'master' into sbt-project
Rename test H2 db in play-slick-iteratee-sample to match project name
Remove unnecessary typing of implicit Session
Remove sample project evolutions from .gitignore!

No wonder the database table didn't exist. Evolutions had been removed!
Re-add sample application evolution files.

It appears that most of them no longer matter, as they have a comment
that says to enable Evolutions if you desire to use them. They are still
useful illustrations for the samples.

For play-slick-iteratees-sample, however, the evolution is still
necessary in order to create the table. And this is why the test was
failing!
