Fix typos in normal modal and intuitionistic logic - #434

- In normal modal logic tableaux soundness, the countermodel must
falsify A: use \mSat/{M}{!A}[w] instead of \mSat{M}{!A}[w].
- Same fix in intuitionistic logic tableaux soundness.
- In complete-consistent-sets, completeness gives \lnot !A \in \Gamma
when !A \notin \Gamma.

This fixes three typos that change the intended logical meaning:
The countermodel should falsify$A$ , so $M,w \models A$ should be $M,w \not\models A$ .
if$A \notin \Gamma$ , completeness gives $\neg A \in \Gamma$ , rather than $A \in \Gamma$ .
