Update testSetup health check to make sure this is off for live sites.

I experimented with this, and it doesn't work well for at least 2 reasons:
- Lots of unneeded line breaks still persist
- Not all parameters are put on their own line in code, and don't want to enforce them to be


Here's the diff I made during my testing...

'keep' parameters are placed inside URLs in order to give Composr some extra information when loading a page. Their URL-presence is automatically relayed/preserved in all Composr links within the page. To enable a 'keep' parameter, simply append [tt]&<name>=1[/tt] to the URL (replace '1' if appropriate, but usually we do use '1' to enable). If there are no parameters in the URL and URL Schemes are not enabled, use a '?' instead of a '&'.

The 'keep' parameters available are:
- - [tt]keep_cache[/tt] -- set to '1' to temporarily enable caching or '0' to temporarily disable. You can also use [tt]cache[/tt] so it works on a per-page basis, with the exception of this not affecting the template and language caching.

- [tt]keep_no_dev_mode[/tt] -- set to '1' to disable development mode (which only runs if you're working out of a subversion repository anyway)
- [tt]keep_hide_dev_mode_message[/tt] -- set to '1' if you don't want the "Dev-mode is on" message to show if dev-mode is on (maybe you're taking screenshots?)
