0e6b3a922a Add commands for forcing preferences during search 
Add commands:

(prefer <formula>)
- will instruct case split queue to assign formula to true.
- prefer commands added within a scope are forgotten after leaving the scope.

(reset-preferences)
- resets asserted preferences. Has to be invoked at base level.

This provides functionality related to MathSAT and based on an ask by Tomáš Kolárik who is integrating the functionality with OpenSMT2
