Banner for 18-Oct upgrade
Proposal to reactivate the upgrade notice banner on the website.
Banner content was discussed in a previous issue - #752 (closed)
Based on that, the wording would be something like: To continue using Monero, ensure that your software is up-to-date with the October 18th network upgrade.
(Along with a link to the download page)
Thanks! I'm not sure how to do this, otherwise I'd offer up a PR that activates it.
