Need to tidy up Mahara so that it better reflects the W3C standards

[Robert Lyon]

Running a page through https://validator.w3.org/ shows that there are HTML issues that we should cleanup

[Kristina Hoeppner (kris-hoeppner)]

How to test:

1. Go to the validator and the tab "Validate by Direct Input".
2. Copy and paste the entire page source of the Mahara page you'd like to run through.

Expected result: No warnings or errors.
Actual result: Lot of warning and some errors. The warning are esp. around Javascript as the notation changed for it.
