Closes#152, Saved Searches (interface layer)
For now, advanced search IS a saved search.
There are still bugs. The 'search' icon is ugly. I wanted to get it out there, however.
Closes#128, Display files as children of item in items list
Fixes#132, On Full-screen mode, browser content disappears but Scholar content does not stretch.
Fixes#133, When Scholar on top, pane automatically resizes depending on item info height.
