Special quote filter for CCMatrix and CCAligned

[XapaJIaMnu]

A reminder to myself to fix in the near future

CCMatrix and CCALigned contain a lot of quotes that are cut off arbitrary on both sides. Sometimes one side will have quotes and the other won't or one side would start with a number and the other won't. Same for the end of the sentence. Perhaps a filter can be added that will "fix up" those sentences by removing superfluous quotes from both sides when they are mismatched.
