Add chrome build to nightlies
In #119 (closed) we introduced ABP UI Nightlies. Because the Chrome Web Store can be quite aggressive when it comes to duplicate extensions (see discussion here) we decided to not publish the nightlies in the CWS but because installing an extension from 3rd party locations is no longer possible and using an unpacked extension requires a few more additional steps we decided initially to not build any nightlies for chrome. But as it turns out there is demand and people willing to use unpacked chrome extension so we'll also build nightlies for chrome.
What to do
Also build nightlies for chrome.
