ui: process tcell events in a separate go routine from rendering

Browse source 
The UI runs off a 16 ms ticker. If no render is required, and no event
is seen, aerc waits 16 ms before checking for new events or render
requests. This severely limits handling of events from tcell, and is
particularly noticeable on pasting of large quantities of text.

Process tcell events in a separate go routine from the render loop.
