Different behaviour from DuckDuckGo when no whitespace before !

[Visne]

In DuckDuckGo, when searching abc!b it would search "abc" using Bing. This addon however just searches abc!b in the default search engine. I can see how this could be considered a feature, but in my opinion its mildly annoying as I am used to how DuckDuckGo works, and I often carelessly put no space before the !. I my opinion, it would make sense if this addon would emulate DuckDuckGo as closely as possible.

I added this to the latest development version. It would be great if you could try it out!

With the development version bangs don't seem to be working at all, yet I think the addon is installed correctly because "startpage.js loaded" is printed to the console.
