No webpage thumbnail cache

[TriVoxel]

Description

Webpages have thumbnails when you have loaded them. What I mean by this is their appearance in the "Tangram" tabs menu. Once loaded, the tab has a small preview of the webpage. However, when you close the app and re-open it, there are no more thumbnails which can make it tricky to tell the tabs apart quickly. Therefor, I think it would be good to cache the thumbnails, and replace them once the page has been loaded again. This way, the user always sees a preview of their webapps instead of an empty gray tile.
