Minimum UI changes page for desktop app beta

[ikreymer]

Related to #4, what are the minimum UI changes needed for desktop app to be beta tested, besides user settings, to make it more clear its a desktop app? Mostly everything works, but perhaps more distinction is needed (eg. no need to set collections to public?)

• Making it more look like a local application:
  • [x] remove footer
  • [x] Show version/build number on main screen
  • [ ] mark outside links with some symbol?
  • [x] top bar distinction @patshiu
  • [x] think about logo for player vs app @patshiu
• menu bar
  • [x] remove features that do not work
  • [x] leave in About, File→Open ^O, File→Quit ^Q, and toggling dev tools via View.
• user menu
  • [x] remove "signed in as"
  • [x] change "space used" graph to show size of WR collections and space available on the drive that holds the collection
• Account Settings
  • [x] Remove everything, except for showing size and free space on drive and a label showing the storage path. (At some later point, this could become a button to select the storage path.)
  • [x] Keep a delete content section to remove content folder
  • [x] Read only display of content directory
  • [x] Merge player about page e.g. stack version, debug info
• change some wording:
  • [x] "upload" → "import"
  • [x] "download" → "export"
