Simplified the command -v syntax, and added a sleep 3 timer to the first execution of the log rotation. The second execution was being issued while the first was still running, thus it would fail and you would have to issue the "Flush Logs" command a second time.
* Provide remote hashes for comparison
* Use double braces for all conditions (for consistency)
* Suppress potential "cd" error output
* Provide "not applicable" output upon any hash request for FTL
While testing to make sure `pihole -v` would output `pihole-FTL version`, I noticed some options didn't work how I expected them to. For example, if I use `pihole -v -p`, I would expect to see the version output of Pi-hole Core. Instead, I'm informed that it's an invalid option.
I've had the following things in mind while rewriting this:
* I'm operating under the assumption that FTL is only installed if the Admin Console is (Line 113 exit 0)
* I have modified the help text to only output with `pihole -v --help`
* I have modified all output to be more similar to the output style of `grep` and `curl` (Ditching ":::")
Testing output:
```

Implement "Halt system" button, next to "Restart system" button, on
admin/settings page. Useful for doing clean shutdown before powering off.
(This affects 4 files, 3 for the web content, 1 for backend script.)
