Allow custom bangs with no queries on search widget

[dracarys18]

Currently let's say I have a custom bang !jenkins. The search won't allow me to press enter untill I write some query in front of it like !jenkins 123. Which is kind of unnecessary because bangs could be without queries as well.

So I would suggest to have the flow like this, when you enter something in the search bar

• Check if it's a part of custom bangs, if yes replace it with URL
• Otherwise go to your search engines, Google,duckduckgo etc.

I am happy to contribute, just let me know if what I am saying makes sense
