Validator options with quotes get escaped and never unescaped

[dstockto]

If you put a validator option with quotes and save, it will be saved with the quotes escaped with backslashes. If you later go into the apigility admin interface and save again, the backslashes start multiplying. The interface shows backslash escaped quotes from the first time they are entered and it seems that they are sent back through in this escaped mode where they are escaped over and over again.

The config arrays are written using single quotes so technically the double quotes should even need to be escaped at all when writing the config arrays.

Will be fixed as part of the fix in zf2: zendframework/zendframework#5757
