TRegExpr update: 1.158 to 1.169

Martin Friebe did great work on TRegExpr in its official repo (with my small help): https://github.com/andgineer/TRegExpr

Change log: https://github.com/andgineer/TRegExpr/blob/master/History.txt

Please merge it. i think it's best to point you to the official repo, instead of giving big patches. Like I did it previous time of TRegExpr update.
