UI Improvement Request: Get rid of JS alert() up for 'No Videos'

[twohlix]

JS Alerts are notoriously bad for UI.

• They block the browser: if I'm using reddit.tv and find a section with no videos, I literally cannot use any other tabs in my browser until I click 'Ok'
• Halts javascript execution
• Prevent's reddit.tv's use of arrowkeys to browse around. The enter key has to be used for alerts. Doesn't sound like much until you're using reddit.tv with a remote, or just a mouse.

Generally its just bad for the UI and incredibly annoying when using down arrows to jump through categories. I'll take a look at the code and try and get an alternative in there and issue a pull request. Just making sure the issue is written down.
