Resolve "LCM text literal operator improperly escapes quotation marks in text"

Fixes literal text operators escaping single quotes (') instead of double quotes (").

This fix partially breaks some OSM operators that expect their inputs to be raw text inputs which was only the case previously because of this bug. I think it still makes sense to fix this behavior since some real inputs need to be properly escaped, and then fix the behavior of the OSM operators.

Closes #44 (closed)
