Tooltips for resources and activities are not informative and need description

When hovering over the name of a resource in the course view, all I get is 'Resource' despite there being a very useful description written in the update resource screen. This is not very useful (although it is great to have this behaviour when hovering over the icon next to the name). I really want to know more about the thing I am hovering over.

It would be very helpful for navigation (and I think trivially easy) to make the tooltip display 'Resource: [resource description]' or just '[resource description]'

This also applies to every other module - truncated summaries as tooltips should be standard behaviour.
