GeoSlick doesn't work properly with IntelliJ

[pkukielka]

Everything seems to be compiling properly, but if you will try to edit code which uses GeoSlick with IntelliJ then you will see a lot of red color ;) It is because of this fragment:

class SimpleQL extends super.SimpleQL with Implicits {
    type Postgis = PostgisDriver.Postgis
    type PostgisTable[T] = PostgisDriver.PostgisTable[T]
}

// (...)

override val simple = new SimpleQL
import simple._

I'm not sure if overriding val here is so good idea. It's quite similar to cake pattern, where def should be always preferred. If you would change this code to something like that:

class ExtendedQL extends super.SimpleQL with Implicits {
    type Postgis = PostgisDriver.Postgis
    type PostgisTable[T] = PostgisDriver.PostgisTable[T]
}

// (...)

val extended = new ExtendedQL
import extended._

and then fix few imports, then IntelliJ will be fixed.
And I think it will be also safer, since there will be no risk of some weird name collisions.
