* ATOM button display is now configurable using the SHOW_ATOM variable in index.php or data/options.php (defaults to false)
* Fixes https://github.com/shaarli/Shaarli/issues/24
jQuery has been removed from all pages, except those who really require
it (like autocomplete in link edition).
Immediate gain: All pages weight 286 kb LESS ! \o/
Highlighting in search results has also been temporarly removed (and
will be re-implemented).
* QR-Code generation now uses a client-side javascript library instead of an external service. This is better for user privacy.
* Library used is http://neocotic.com/qr.js/ (11 kb).
* jQuery is no longer used to display QR-Code (this is a first step in removing jQuery entirely).
* This library is loaded *only* if the QR-Code icon is clicked.
* If javascript is disabled, it will fallback to the external service.
* External service was changed from "invx.com" to "qrfree.kaywa.com" because invx has become bloated.
By loading the javascript library *only* if the icon is clicked, it will prevent the 11 kb lib to be loaded in every page.
Title : Shaarli Vulnerabilities

Affected versions : master-705F835, 0.0.40-beta (versions below may also
be vulnerable)
Vulnerabilities : Persistent XSS & Unvalidated Redirects and Forwards
Persistent XSS :
- During the instalation or configuration modification, the title field
is vulnerable. e.g <script>alert(1)</script>
Quotes can not be used because of var_export(), but String.fromCharCode
works
- The url field of a link is vulnerable :
When there is no redirector : javascript:alert(1)
Then, the code is triggered when a user click the url of a link
Or with a classic XSS : "><script>alert(1)</script>
Unvalidated Redirects and Forwards :
A request with the param linksperpage or privateonly can be used to
redirect a user to an arbitrary referer
e.g
GET /Audit/Shaarli/master-705f835/?linksperpage=10 HTTP/1.1
Host: 127.0.0.1
Referer: https://duckduckgo.com

Shaarli uses light Javascript in its normal operation, and some jQuery
for some features (autocomplete in tags, QR-Code popup...).
jQuery can be slow on small computers. An option has been added in
configuration screen to disable javascript features which are hard on
CPU.
(Note that the Picture Wall is awfully heavy *without* jQuery.)
(Side note: A *LOT* of users want Shaarli to work without javasript at
all, if possible. That's why I try to use as few javascript as possible:
It keeps Shaarli pages fast.)
