[t3314] Add thumbnail to project settings tab
Wire up droping images storing data on the server to use as thumbnail
Changes for thumbnails added via URI
Review fixes + missing functionality to save data uri images on initial project creation
Fixes for initial project creation and if the thumbnail is a data uri
Separate out old share editor code into new tab layout
Forgot loading from dashboard/remix
Added tooltips to indicate if share/embed/view-source tabs were interactable or not. Still needs better toggling
Use state flag to prevent unwanted tab clicks
Better listeners for inputs
Review tweeks on titles. View source is a button rather than a tab
