Increase debounce time, add flush on blur, ui tweaks

[eatonphil]

Typing is janky because of waiting for updates. This PR does three things for that:

• Wrap http updates in a setTimeout to make the UI not freeze on updates
• Bump the update interval while editing text/code from 125ms to 3s
• Flush updates to text/code onblur and on ctrl-enter in panels

This PR also updates the UI

• Switch to ionic fonts
• Soften the UI
• Drop group labels
• Buttons to automatically create graphs and tables
  • Should probably be more contextual (near Result/Preview section?)
  • Maybe make preview section not black
• Fullscreen mode for panels
• Line wrap on code editor
• Automatic resizing on code editor (bugfix)
• More state synced to url (expanded, sidebar open)

Notes:

• Always reading from localstorage on desktop (urlstate) is too slow (changing pages for example)
• Filter aggregate panel is very tall vertically when exposed
