Subject: peniquitous.js: Try to listen for & simulate key events

Doesn't quite work. We're correctly listening for Ctrl-N/P presses, and
seemingly correctly simulating corresponding up/down key presses, but it
seems that the 'content scripts' can't trigger page events.

See
https://developer.chrome.com/extensions/content_scripts#execution-environment
which describes the "isolated" execution environment of Chrome content
scripts.

Spent a while trying to figure out why this wasn't working. Finally
looked back through my Chrome console history and found out what I did
previously to get it working and it turns out that was the same thing
I'm doing here. Finally had a moment of inspiration that prompted me to
look into the different execution environment thing.

Found a useful Stack Overflow post that descibes how to inject a script
onto the page, which will give me access to the page's context:
http://stackoverflow.com/questions/9515704/building-a-chrome-extension-inject-code-in-a-page-using-a-content-script

Doing that should get this working, so that's what I'm going to try
next.
