* Add [.] key to enable timer
* "Loading..." message turns red and italic when timer is active
* Press [.] key to disable timer.
After a bit of experimentation, 5s seemed optimal: 2 seconds would cause
the imgur api to trip if the app is used more than once at a time; 5
seconds is enough time to view the image without feeling particularly
slow.
Maximums:
1 images in 5 seconds
3600 images in 5 minutes
43200 images in an hour
* There is probably a much nicer way of doing it (perhaps a better
hash)?
* Added a counter to the imgur random page counting the number of
[Facebook Monopoly Men](http://i.imgur.com/3Tt6N.gif).
* Added the md5sum of the current image to the getRandomImage api call.
* Future functionality might be storing every image md5 in an array and
counting duplicates, instead of the current check-against-known-dupes.
