Make compatible with Trac 1.2

[tim@…]

I found I had to make a javascript tweak in order to get this plugin to work in my Trac 1.2.2 installation:

--- tracsectionedit/htdocs/js/tracsectionedit.js       (revision 2737)
+++ tracsectionedit/htdocs/js/tracsectionedit.js       (revision 2738)
@@ -10,6 +10,6 @@
        }

        $(document).ready(function() {
-              $("#wikipage >:header").addEditlink("Edit this section");
+              $("#wikipage > h1,h2,h3,h4").addEditlink("Edit this section");
        });
 })(jQuery);

Without this patch, not only wouldn't the plugin work, but other javascript-related stuff on the page didn't work properly, like the "Link to this section" tags on the section headings.

Disclaimer: I know almost NOTHING about javascript. The tweak I made above is just something I deduced could work based on perusing around ​https://api.jquery.com/child-selector and ​http://jqfundamentals.com/chapter/jquery-basics. It seems to work fine, although I'm sure someone more familiar with javascript could come up with something more general.

The use of ​header selector should not be a problem.

If you'd like to debug further, please revert your changes, install the latest version from the 1.2 branch (I just pushed some changes), ​check the browser console, and post your findings to the ​trac:MailingList.
