Title: gen_code: Added support for quote_char option.

Can be either ', ", or null (null means choose the one with fewest occurrences in the string, like the previous behavior).

Use case: Serializing data-bind attributes (Knockout.js) into doublequote delimited attributes and avoiding an excessive number of " entities.
