Add anchor button to tinymce

[Robert Lyon]

One of the useful tinyMCE buttons that we currently do not use is the Anchor button to allow one to add anchors to a block of text.

It should be a matter of adding 'anchor' to the plugins and toolbar sections of lib/web.php

and then testing it out to make sure it works as expected

To expand on what Robert said, the "anchor" plugin ships with TinyMCE, and thus with Mahara (it's under htdocs/js/tinymce/plugins/anchor). But we just haven't been activating it.

[Aaron Wells (u-aaronw)]

Hm, maybe we should add a local/lib.php method to let people customize the TinyMCE buttons. Because I can see how, for instance, on mahara.org it would be handy to have the "code" plugin enabled also, but probably most Mahara sites wouldn't care about that one.
