DSL: contains method conflicts with built-in

[danielkza]

As per title, the contains method of the query filter DSL doesn't work at all because it conflicts with the built-in on String.

Damn it! I never really liked the DSL idea and here it comes back haunting.

Simply changing the name of this function will break the associativity with whereContains method of the Querier, so I am currently considering either changing names of both the DSL and whereContains and whereNotContains or finding some smart prefix for DSL which would discern all SORM's implicits.

Suggestions are welcome.
