Automated response: Option to hide the hero slider when site is closed

This patch will add a third radio button for the Site closed option allowing you to close the site and also hide the hero slider.

Also, by default closing the site automatically (e.g. upgrades) will also hide the hero slider. And the Commandr command now supports the ch option for closing the site and hiding the hero slider. The Setup Wizard option on step 9 will NOT hide the hero slider because it is assumed a new site might want the hero slider up to showcase a countdown or "Coming soon" thing.

A hotfix (a TAR of files to upload) has been uploaded to this issue. These files are made to the latest intra-version state (i.e. may roll in earlier fixes too if made to the same files) - so only upload files newer than what you have already. If there are files in a hot-fix that you don't have then they probably relate to addons that you don't have installed and should be skipped. Always take backups of files you are replacing or keep a copy of the manual installer for your version, and only apply fixes you need. These hotfixes are not necessarily reliable or well supported.
