Redesign the user interface (GUI)

Original issues TumblThree#332, TumblThree/wiki

Simplify application usage by re-organizing its layout or even redesigning the application user interface.

Possible enhancements (by @gpriaulx):

• Try to contextualise everything visually. Easier said than done I guess...
• Get rid of textual labels and instead rely on tooltips and layout.
• Show less stuff by default.
• Show more visual feedback.
• Reduce the start/stop/pause/resume concept to just pause/resume. It's either downloading stuff from the queue, or it isn't. Only show the relevent action. EG Pause OR Resume.
• Move the user account to be a 'sessional' thing rather than a 'settings' thing. Still persist it of course.
• Restore previous state with respect to pause/resume, otherwise if new launch with no items just be in crawl mode already such that as soon as something is queued it 'just works'.

Something like this I guess - please forgive my terrible mock and (lack of) design skills:
