Better composer minimize behaviour

[tobyzerner]

From http://discuss.flarum.org/d/396/general-ux/1:

When a reply box is minimized, make mouse hover maximize it, and mouse out minimize it, until a maximize button is clicked again to make it stick up. Good when you're reading another topic with it minimized, but want to check your reply quickly.

To keep things simple, I think we should not require clicking a maximise button, but instead only keep the composer maximised if a text field in the composer has focus.

What needs to be done:

• Alter the Composer component to implement this behaviour. It might be a little complicated, but basically I imagine the steps would be:
  • Change the view's click handler to a mouseover handler that shows the composer if it is minimized
  • Add a mouseout handler that minimises the composer if the text field does not have focus (I think there is already a flag for this)
  • Also add a handler so that when focus is lost from the text field, the composer minimises

Changed my mind about this. It's fine (and intuitive) the way it is 😁
