Partially revert 7a0a9e2156
serendipity_specialchars() and others were made to
return "" when fed something that is not a string.
So boolean values (1 or TRUE) will be returned as "",
i.e. FALSE, breaking the blog in interesting ways
(i.e. displaying wrong configuration values and
saving them to the database).
Closes #476.
