Auto-add domain to domain list everytime user use just-read on webpage

[honeybar]

Hello, this is my first time contributing to open source project. I made changes to content_script.js such that now, every time user use just-read on the webpage, it will check if the domain exists in auto-enable-site-list, and if it doesn't, it will add it automatically, so everytime user visit any page in the domain, Just-read will automatically be pulled up.

Thanks for the contribution! I'll include this feature in the next update.

A few notes:

• I won't be merging this directly because this functionality will need to be enabled/disabled through a checkbox on the Options (-> "Additional options") page.
• I also will modify your approach a little bit to follow the approach mention in the related issue, 'Add this domain to your auto run list' button/hotkey #152, where it will add the plain domain (example.com if Just Read is started on the top level, and add example.com/.+ if it isn't the top level in order to keep the functionality consistent. I've actually already implemented the code for 'Add this domain to your auto run list' button/hotkey #152, I just haven't gotten to merge it into the master yet.
• When contributing to projects like this, you should match the programming style already being used. For you that means adding semicolons and a little bit of white space changes. Don't worry about changing it now because I'll need to make the above changes as well 😄

Thanks again for contributing! I hope it's the first of many of your contributions.
