Annotation "feedback" Javascript breaks on clean-urls and sites in subdirectories

[Aaron Wells]

In artefact/annotation/js/annotation.js, in the function "connectAnnotationFeedbackLinks()", there's a check for "window.location.pathname == '/view/view.php'", meant to make sure that the link only gets activated via Javascript when you're viewing a page.

However, this breaks in two scenarios:

1. If the Mahara site is in a subdirectory. For instance, my own test site sits at the URL http://vegas.wgtn.cat-it.co.nz/mahara/, so my pathname is '/mahara/view/view.php'

2. Clean URLs. If a site has Clean URLs turned on, then the URL to a page will be something like "https://mahara.org/user/aaronw/files-for-sharing", in which case the pathname is '/user/aaronw/files-for-sharing'.

So relying on the suffix of the URL to determine if we're on the right page to run that JS, is not going to work.

What we should probably do instead, is that when the block is being rendered on a page where that link should be Javascriptified, then we should add some inline JS that invokes the connectAnnotationFeedbackLinks() method.

Annotation feedback JS shouldn't rely on window's URL path.

Bug 1431668: This logic doesn't work for sites that are using
cleanURLs, and sites in subdirectories. And anyway, the
annotation.js file only gets loaded on pages where the block
is in "view" mode, so the logic isn't even needed.
