Description
When the blesta config file is written, and the database credentials are saved, special characters are escaped in php strings, like "$". However, the config uses single-quote strings rather than double-quote strings, so some special characters do not need to be escaped anymore, like "$". For example, an apostrophe, "'", should continue to be escaped.
