IdTable.new cannot use SEQUENCE nextVal

[afk11]

Hi,
I opened a PR about adding Long value support to Sequence NextVal.. I decided I'd keep developing using Int instead of Long so I don't have to wait for the PR to be merged.

I've realized I have another problem though - if the table is to be used as an Entity, the id column type is Column<EntityID<Int>> and not Column<Int>. So now I'm a bit lost about how to proceed, but feel it's connected in some way to #1001, so I'd hope that PR can fix both :)

// works today
private object Developer : Table() {
    val id = integer("id")
    var name = varchar("name", 25)

    override val primaryKey = PrimaryKey(id, name)
}

// works with #1001 
private object DeveloperLong : Table() {
    val id = long("id")
    var name = varchar("name", 25)

    override val primaryKey = PrimaryKey(id, name)
}

# doesn't work right now
private object DevelopersTable : IdTable<Int>() {
    override val id = integer("id").entityId()
    var name = varchar("name", 25)
}
