webapp: remind user when using repositories that lack consistency checks

When starting up the assistant, it'll remind about the current
repository, if it doesn't have checks. And when a removable drive
is plugged in, it will remind if a repository on it lacks checks.

Since that might be annoying, the reminders can be turned off.
