Add Image element to OpenSearch document

Add Image element to OpenSearch document
Use a separate 16x16 ico for opensearch

Opensearch limits icon size to 10,000
(and the ico with multiple sizes is too large).
Added dependency graph widget (via Stratopan) GH #1168
Simpler layout does not require dimensions.

I've simplifed the widget so you don't need to
pass height and width dimensions any more. Just
setting the size of the iframe should be sufficient.

Add dependency graph widget (via Stratopan) GH #1168
Use "protocol relative url".

Some browsers refuse (or just warn) when mixing secure and
insecure content.

So now the graph iframe will be loaded with either http or https,
depending on what the parent page is using.

Fix initial load of dep graph to display:none;

On initial load the dep graph ifram and div was overlaying everything, intercepting
clicks and scrolls (At least in firefox). After opening and dismissing it, it worked
and the only difference was that after dismissal, the style had changed to
`display: none;`. Applying `display: none` on initial load fixes the problem.
