Title: [BUGFIX] Always escape backslashes in strings

Backslashes in PHP strings always need to be escaped as two backslashes
(even in regular expressions). There are only two exceptions:

* sequences like \n in double-quoted strings
* escaped single quotes in single-quoted strings (not present in Emogrifier)

Closes #123
