Two single or double quote escapes single or double quote when string is surrounded by same type of quote

[MitchellGale]

Description

Adds implementation for double quotes working to escape a single quote.

Uses string builder to generate query in String Utils. Only escapes quote when outside quotes are matching, does not work for `. Below are examples of how the new queries function.

SELECT 'I''m';          -> I'm
SELECT 'I''''m';        -> I''m
SELECT "I''m";          -> I''m
SELECT "I""m";          -> I"m
SELECT \`I\`\`m\`;      -> I``m
SELECT 'I""''m';        -> I""'m
