dynamic widget load sizes

[azaroth42]

Currently the size of windows must be specified in pixels, which assumes knowledge (if minimal) of the user's screen real estate.
It would be useful to allow keywords or, preferably, percentages in the widget start up, that were applied against the current size of the mirador workspace.

So instead of

{"widgets": [  { "height": 800, "type": "delimitView", "width": 600 } ]}

it would be nice to allow

{"widgets": [ { "height" : "100%", "type" : "delimitView", "width": "30%"} ] }
