b8b3703511 improved implementation of is_qblocked() 
Disabled by default. Has no effect if ran with the default set of
options where qlemmas=true  and instantiate=true

27d8fa4a34 hard-code quantifier weight to 15 
With default settings, the eager threshold is 10 and lazy is 20.  15
puts us in the middle ensuring that lemmas are instantiated when UNSAT
and otherwise delayed.

135a4a765f Adding grounding of the current lemma 
In addition to adding the necessary instance of a quantified lemma,
add its grounding over the global set of skolems.

9f0eb367b1 ground lemmas during propagation when qlemmas are disabled 
When asserting quantified lemmas are disabled, ground a lemma
explicitly during propagate to make sure that it is ground using our
local set of skolem constants.

5da0753269 (spacer) add instances even when a q-lemma already exists 
It is possible that a new instance of a quantified lemma is discovered
even though a quantified lemma it already known. In this case, the
instance should be added to a corresponding context, even though the
lemma is not new.
