added tinyint and smallint as int8 and int16

Hopefully fixes #12

I've noticed with both these Int8, Int16 and Time types, they needed to be added here too,
https://github.com/crystal-lang/crystal-db/blob/master/src/db.cr#L72

otherwise I get the following errror

in src/app/pages/page-repository.cr:105: instantiating 'DB::Database#exec(String, (String | Nil), (Int32 | Nil), (String | Nil), (String | Nil), (String | Nil), (Int8 | Nil), (Int8 | Nil), (Int32 | Nil), (String | Nil), String, String, Int32)'

      res = @db.exec("
                ^~~~

I'm using db v.0.2.0

The failing tests seem to have nothing to do with the code pushed.
Any idea when travis will be fixed and if this change will be merged. Working from by own fork at the moment but it's not ideal.
