Model downloader dialog (#569)

* API core for model downloader

* initial basic dialog for missing models

* app.ts handling for missing models

* don't explode if getModels is a 404

* actually track downloads in progress

* overall pile of improvements to the missing models view

* minor fixes

* add setting to disable missing models warning

* temporarily remove 'models' entry from default graph

to avoid missing model dialog causing issues. Also because ckpt autodownloading shouldn't be allowed

* swap the url to a title

* add model directory to display

* match settingStore commit

* check setting before scanning models list

ie avoid redundant calcs when setting is disabled anyway
