Improve Orderbook UI

[dib542]

Improve the Order card to be simpler and clearer:

• no slider
• Swap/Limit radio group
• Buy/Sell radio group
• limit/market price has its own input group
  • full sentence explanation of what the limit/market price is
  • shortcut buttons for prices: "Market", and +/- 1/5/10%
• add separate input/output amount controls as input groups
  • visually represent the directional flow with an arrow and text: "You pay" / "You receive"
  • allow switching the direction of transfer by clicking the arrow
  • allowing editing both input/output text inputs at the same time
• add order expiry via a button group (all options clearly visible), options: "None", "1 day" ,"1 week", "1 month", "1 year", "custom"
  • custom input can be the current text input + time period type selector: "seconds"/"minutes"/"days","weeks","months"

Also adding improvements from other issues into this PR, a general improvement to the entire Orderbook page
