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.

Needs some testing, I am not sure how to solve the case now where "no category" shall be used. It will always fall back to the default category.
Probably if someone uses a default category, that's the intended behaviour?
Iconfont icons are of no value to screenreader users; in our case,
they get alternative text. By adding 'aria-hidden="true"' to the
<span> holding the iconfont icon, we avoid the screenreader trying
to announce the iconfont icon.
Should've been tested in the alpha, but given the problems with the preview logic (see http://board.s9y.org/viewtopic.php?f=3&t=20791) I'm convinced we need this now. This mainly reworks serendipity_getTemplateFile to follow a simple scheme on where to look for templates – either in the backend or frontend, based on where we are but overridable, then in the engine, then in the defaultTemplate as fallback.
A first approach at fixing s9y for php 7, which makes it possible to
write an entry without any error message. The specific changes are: 1.
__construct for the plugin classes 2. Update Cache Lite to a modern
version to fix its similar constructor problem 3. Remove the
session_regenerate_id call from the session destructor (should get
re-added to session creation where necessary) 4. Remove error handler to
prevent silenced warnings from becoming fatal exceptions
