Tool for opening browser during development

[aklinker1]

Right now, web-ext is the only tool for opening all browsers with an extension installed. Unfortunately, it is quite heavy and does a lot of other things unrelated to this process. It also has lots of peer dependencies, all of which are optional, but annoying when the warnings pop up on install.

To start out, this tool needs to do a couple of things:

• Open Chrome with an extension installed
• Open Firefox with an extension installed
• Reload the extension without reloading the browser

This will do everything web-ext does for this one use case.
