Subject: Big update for the editor!
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=b3d3ca5b79233687bbd20fa31563b66dc8ef9860;p=moodle.git

Big update for the editor!
Code is closer to HTMLArea 3.0 RC1.
- Updated dialog behavior (no more showModalDialogs)
- Cleaner XHTML coding in dialogs
- Unnecessary comment stripped off from htmlarea.php
- New anchor feature.

-	 *   cfg.toolbar.push(["linebreak", "my-hilite"]); // add the new button to the toolbar
