Found a few typos which could be updated.
I tested the Configuration page change by navigating to /config and verifying the page title set in the browser as well as the page title text on the page
I verified the Conduit error message by navigating to /auth/start/?__conduit__=1
The CircleCI error message was not verified due to the involvement of testing with CircleCI however the change is very minor and has very little risk of impacting any functionality.
Oh, just for completeness -- you can trigger the first message by visiting this URI while logged out (e.g., in an incognito window):
The third message requires setting up a CircleCI build step in Harbormaster for an observed, non-GitHub repository. This is almost certainly not worth actually bothering to reproduce.
